Silver And Gold Bullion Coins

Collecting silver and gold bullion coins can be an investment, combines an insurance against market inflation and a hobby passionate a person. Accumulating silver and gold coins are the easiest way for you start to own gold and silver. Many of the bullion coin series which have multitudes of designs created with outstanding craftsmanship, so silver and gold make very desirable objects.

Since the first bullion coin published in South Africa in 1967, and then a lot of national exhibitions in the world have their own gold coins series. Very most popular the British Britannia series, from gold coins the Chinese Gold Panda Series and the American silver Eagle. 

Most silver and gold coins never used in daily trade (some gold coins such as the Krugerrand have no face value!), despite that many of the bullion coins issued today are bestowed with legal tender status in their respective country of issue, therefore making them exportable to most of the countries worldwide without being subjected to import taxes, duty or VAT.

This fact makes silver and gold coins a very appealing means for  ownership of gold and silver in private. Investors put their money into gold and silver coins to balance off  the effects of inflation because the value of the two metals have more or less since increase consistantly in the last five years. 

Then again, it is noteworthy that since many bullion coin series, especially designs change every year and have very limited edition, many  bullion coin series less than 100,000 units per year. This leads be accessed due to its rarity and collectible value in some bullion coins significantly higher prices at the top of their market gold content. 

Therefore tend investors for gold coins looking to who repetitive design during its annual issue, significant influences and command have not a high premium, such a Nice example is the South African Krugerrand coin when it first issued was to pick up the South African Krugerrand a premium no higher than 5% of its gold content, and the premium less than 1% above from in their market price of gold 

Here are some tips to keep your silver and gold coins collection to start : 

1. Are you an investor or collector? This is the major factor that will influence which coins to buy and which coins to “admire only”. Furthermore, caring for rare collectible bullion coins requires more technical expertise and some considerable investment in keeping your collection in pristine condition (but well worth the price).

2. bullion coins are not a recipient of money fast, they are kept for years, before even trading or reselling them. When your collection grew, investments in safekeeping a hidden safe in the Home or in the vault of bank deposits can also be used.

3. For starters, silver bullion coins are a nice idea as they are cheaper, so you can an impressive collection in a shorter time (and with less budget!). 

4. Concentration in the collection on a few types of gold coins as a starter, the market may be full of forgeries and fraud, read approximately the series of gold coins you gather to tell certain facts such as sizes, purity, designs of the coin as well as special issues (eg there is such a thing as a silver Krugerrand ), you can easily help to identify which is a deal and which is a scam.

5. If you buy from your local coin dealer, the first take the time to check the background your dealer , whether they are known and trusted in your area or your neighborhood?  Do they offer Fair advice and friendly service? 

6. When buying online, the best method is to start buying from auction first before going to individual shops, as auction website such as ebay have feedback system tracking the past sales of the particular seller, giving good indication on whether the seller provide good service, or whether they have sell similar items in the past and of course whether they provide good quality wares. And the large market of auction websites with numerous sellers can give comparison of the prices of a specific coin

Gold and Cadmium

Gold is a precious metal. This metal is liked by all people world wide. Recently the rate of gold has been rising up steadily and the prices of other commodities is calculated according to the rate of this yellow metal. Countries trade with one another, paying in the form of gold. Of all the trophies given in games, competition,and other activities, gold has the first place. Ornaments takes the first place in marriages. It is a solid asset which has liquidity, and helps at hard times.

What makes this gold metal valuable?

Its glittering yellow colour never fades, just as its value. Gold has flexibility and can be treated to thin sheets or wires. It is mined from the hidden rocks found underneath, and the cost for processing the metal is time consuming and very costly.

Golden bars or coins are otherwise called as Bullion. Bullion are mined by certain countries and sold in the world market. Bullion are pure gold which is 24carat. 99.9% purity is common. It is not possible to make ornaments out of 24 carat gold bullion.

24 carat gold is lessened to 22 carat and thus transformed into jewels. 24 carat is a mixture of copper and silver metals. these metals are combined in 2:1 ratio. the carat rate and value of gold decreases if the metals are added more.

Cadmium

Cadmium is a metal. This metal is mixed with gold to make ornaments and is considered to be pure. The world gold council has a hallmark for pure gold. With the addition of cadmium it is named as 916kdm. Cadmium added gold is considered pure because the cadmium added jewels when reheated or beaten up nothing is lost, and the result we get is pure gold.

When 916 kdm gold is heated,the Cadmium metal evaporates into the thin air in the form of gas. This gas is toxic.cadmium content gold does no harm to the wearer. 916 kdm purchased gold has a resale value, if it is bought as an asset.

Purchasing of gold is a very good mode of asset and its value increases day by day, so the craze for gold never fades as its value and colour,so it is necessary to know the relation between gold and cadmium. All that glitters are gold, and the value of this asset increases, only if the correct ratio of silver and copper are added.

Different Types Of Mining Processes

Mining has become a controversial industry because of its “devastating” effect to the environment and the ecosystem. However, it has contributed so much to civilization that without it, we could never be where we are today in many aspects.

There are two basic methods of mining. These are the surface and the underground mining processes:

1. Surface Mining

This involves the mining of minerals located at or near the surface of the earth. This encompasses at least six processes and these are:

• Strip Mining – this involves the stripping of the earth’s surface by heavy machinery. This method is generally targeted at extracting coal or sedimentary rocks that lay near the earth’s surface.

• Placer Mining – this involves the extraction of sediments in sand or gravel. It is a simple, old-fashioned way of mining. This method is generally applicable to gold and precious gems that are carried by the flow of water.

• Mountain Top Mining – this is a new method which involves blasting of a mountain top to expose coal deposits that lie underneath the mountain crest.

• Hydraulic Mining – this is an obsolete method that involves jetting the side of a mountain or hill with high pressure water to expose gold and other precious metals.

• Dredging – it involves the removal of rocks, sand and silt underneath a body of water to expose the minerals.

• Open   Pit  – this is the most common  mining  method. It involves the removal of the top layers of soil in search for gold or buried treasure. The miner digs deeper and deeper until a large,  open-pit  is created.

2. Underground Mining

This is the process in which a tunnel is made into the earth to find the mineral ore. The mining operation is usually performed with the use of underground mining equipment. Underground mining is done through the following methods:

• Slope Mining – it involves the creation of slopes into the ground in order to reach the ore or mineral deposit. This process is generally applied in coal mining.

• Hard rock – this method uses dynamite or giant drills to create large, deep tunnels. The miners support the tunnels with pillars to prevent them from collapsing. This is a large-scale mining process and is usually applied in the extraction of large copper, tin, lead, gold or silver deposits.

• Drift mining – this method is applicable only when the target mineral is accessible from the side of a mountain. It involves the creation of a tunnel that’s slightly lower than the target mineral. The gravity makes the deposit fall to the tunnel where miners can collect them.

• Shaft method – this involves the creation of a vertical passageway that goes deep down underground where the deposit is located. Because of the depth, miners are brought in and out of the  pit  with elevators.

• Borehole method – this involves the use of a large drill and high pressure water to eject the target mineral.

These are the basic methods used in the extraction of common minerals. There are more complex systems, but still, they are based on these fundamental processes.

Gold Mining In The Carolina Slate Belt

The Carolina Slate Belt is a gold-wealthy strip from Virginia, south through North and south Carolina and ends up in Georgia. Numerous rivers and streams in this area  contain placer gold deposits. Although most people in the US knew of the gold  as a result of the gold rush California, the first gold discovery in the United States in North Carolina was within the Carolina Slate Belt. Gold was first discovered in the United States in 1799 in the Little Meadow Creek in Cabarrus County, North Carolina. 

Although this discovery was not as much attention as the discovery California , In fact most of the experienced gold miners who moved to California, during the California Gold Rush had honed their skills mining areas along the Carolina slate belt. After the first gold find some other discoveries in shale and thus more gold mines were developed. 

Geology In Carolina Slate Belt 

The Carolina Slate Belt majorly composed and derived from rocks that were deposited from volcanic eruption on the surface of the Soil and then sedimentation. The slate is thus characterized by low grade metamorphism that a Large number of rocks is a slaty cleavage here.

Inside Piedmont for the most part consists  and often occur from metamorphic intrusive rocks such as various types of gneiss. The whole region Piedmont is underlain at a depth of Approximately 20 km from a region, the seismic waves reflected emphatically.

This area is often regarded as a series of faults along the upper part, including the uncovered portion of Piedmont, moved westward over a number of completely unknown rocks. The error may twist upward toward the west and rise to the top as one of the various thrusts in the Appalachian Mountains.

The slate is made up of low grade metamorphosed volcanic and slate cleavages. The mountainous Piedmont of North Carolina isolates the Triassic-Jurassic rift basin and the level Coastal Plain from the hilly Blue Ridge and Appalachians. 

The coastal plain consists of Mesozoic-Cenozoic sediments created when the North Atlantic got to be wider and the Triassic-Jurassic rift basins of sedimentary rocks in the plan during the opening of the Atlantic Ocean formed. The Raleigh Belt and Eastern slate belt containing rocks Love that of Piedmont. However, these are only exposed to the east of the Triassic-Jurassic basins and their connection to the Piedmont is not entirely clear.  

The Piedmont can be divided into two parts, the western and eastern areas of both the two very different rock suites. The eastern part is the Carolina Slate Belt, while the western part is often referred to as the interior of Piedmont.  A number of geologists often combine the Carolina Slate Belt and Inner Piedmont, what is commonly known as the Carolina Terrane 

Two of the most important gold mines in the Carolina Slate Belt included :

Haile gold mine
 

The mine developed from a gold deposit, which was discovered in 1827 on the farm owned by Benjamin Haile in Eastern Lancaster County near Kershaw, South Carolina. The mined operated until the early 20th century operated when the gold deposits originated. This mine was one of the most productive gold mines during the years. 

The Dorn Mine

This is another Large mine in the Carolina Slate Belt. The mine is located in McCormick County, South Carolina. Gold in the mine was first discovered by William soon began Burkhakter Dorn in 1952. The mining at the mine after Dorn and lasted more than 120 years. The slate has several other mines quite a significant amount of gold. In fact, most major gold mines in North and South Carolina Located on the Slate. 

There are numerous other smaller placer mining are found throughout Virginia, North Carolina, South Carolina, and Georgia. All of the gold-bearing areas most rich within these states are found in the slate belt.

Mining has been done in this area for over 200 years, but there are still Nice amounts of gold in the streams and rivers in the Carolina Slate Belt are found.

Source Of Gold Ores

Gold and silver metals are obtained from a variety of different types of rock ores. Most people think of gold nuggets constitute the source of the gold. But the reality is very few gold derived from the nugget. Nearly all newly mined gold comes from ores from natural hard rock mining, fine gold grains, even microscopic particles. 

Gold widely found in nature, although it is one of rare metals. It often happens gold which known as the native metal encased within a mineral such as quartz. And historically gold the most productive, occur in the vein deposits. Currently these widespread deposits give much of the world gold ore. 

The element gold ores in nature occurs even mainly in the form of native gold, In various gold ores, original gold mineral content commonly occurs, fine mineral particles and small contained within sulfide minerals such as pyrite.

Iron pyrites a very common mineral associated with gold, but it also serves as a reducing agent. Therefore, if gold is found enclosed in pyrite, it is always free gold and not as some kind of gold sulfide. Gold also sometimes in chalcopyrite, galena and arsenopyrite and stibnite, but not as one is found in such quantities as may be found in pyrite. Other minerals such as sphalerite, pyrhotite, magnetite and hematite sometimes carry little amounts of gold as well. 

Gold also comes as Telluride as Calaverit. Common gangue in gold ores include quartz, fluorite, calcite and pyrite, but many others can be found in smaller amounts

Gold Ore Minerals :

The most prominent is pure gold – The most common the native gold contains a Little amount of silver, copper, platinum, etc. 

Telluride minerals are the most common minerals that significant gold in their makeup. These include:

• Petzite (Ag, Au) 2, Te,
• Hessit (Ag2Te)
• sylvanite (Au, Ag) Te2
• Calaverit (Au, Ag) Te2
• Krennerit (Ag2Te, Au2Te3)
• Nagyagit ( Au2, Pbi4, Sb 3, TE7, S7). 

The gold containing sulphides and tellurides, are primary formation from gold ore, although auriferous chalcopyrite could be formed by secondary enrichment process.

Native gold can occur in the primary, secondary enrichment or oxidized zones. The tellurides, which are usually associated with pyrite, are widely used, though not so often, but not always recognized; in fact, some of the miners they are mistaken for sulfides  

Common types of gold ores

Gold deposits are often classified according to their association. 

1. Of these can be cataloged as quartzose.

This means that the gangue mineral is acid, that is, quartz and fluorite which may be very abundant or the other gangue minerals of the alkaline soil group. Not infrequently, it seems varies pyrite and limited amounts of chalcopyrite and galena within quartz quantities. These are free milling ores.

Through a free milling ore it is meant that the rock does not require roasting before the gold can be recovered therefrom. Dry ore is the term that is often used for this category. 

2. Copper ores containing gold ore mineral

These are widely used in the United States and much of the chalcopyrite is gold bearing. This auriferous copper ores are particularly abundant in Colorado, Utah, Montana and British Columbia. They are also in Gold Hill, North Carolina and in Canada to Newfoundland. 

3. The class of gold ore is auriferous lead ores.

The proportion of lead in these rocks is large and the gold content is often low. They are refractory ores such as copper ore. The refractory ore is a meant requires roasting before extraction processing. The heavy sulphides as copper, lead and antimony require this method of treatment, that is the condition of the gold in the mineral will not allow of its immediate capture with most recovery systems.

4. gold ores comprises the gold-telluride group

The gold telluride ores occur accompanied by other tellurides with silver, lead and antimony or as native gold accompanied by other tellurides.  These ores are often sent directly for the treatment of smelters. 

5. Type of disseminated ore.

They are often low in grade, but present in very large numbers. They fill large fracture and fault zones or replace certain geologic horizons. They are the result of the circulation of large amounts of heated water deep underground.
