Find Gold Prospecting In Beach ( Videos )

Gold prospecting in beach is an accumulation of valuable minerals formed by gravity separation during sedimentary processes and in geology called placer deposits . Beach placers form on seashores where wave action and shore currents shift materials, the lighter more rapidly than the heavier, thus concentrating gold .

Placer environments typically contain black sand, a conspicuous shiny black mixture of iron oxides, mostly magnetite with variable amounts of ilmenite and hematite. Valuable mineral components often occurring with black sands are monazite, rutile, zircon, chromite, wolframite, and cassiterite.

Among the examples of beach placers are the gold deposits of Nome, Alaska; the zircon sands of Brazil and Australia; the black sands (magnetite) of Oregon and California; and the diamond-bearing marine gravels of Namaqualand, South Africa.

Test Of Copper Ore With Sulfuric Acid ( H2SO4 ) Videos

Copper extraction techniques refers to the methods for obtaining copper from its ores. The method used to extract Copper Ore depends on the nature of the mineral ore. Sulphide ores such as chalcopyrite are converted to copper by a different method from silicate, carbonate or sulphate ores.

Copper can be extracted from non-sulfide ores by a different process . Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulfuric acid to produce a very dilute copper sulfate solution.

Chuquicamata The Largest Open Pit Copper Mine In The World ( Video )

The Chuquicamata mine is The largest open pit in the world with mining production Copper, gold an silver, and copper as the main product. The mining operations carried out by Coldeco at once owner of Chuquicamata mine in Chile and  Open pit mining in this Chuquicamata  is estimated to have a length of approximately 4.3 km , with  3km wide, with a depth of about 850m and Chuquicamata is also the largest open pit copper mine in the world

Chuquicamata (choo-kee-kə-MAH-tə), or as it is more familiarly known with "Chuqui" , located 16 km from Calama at 2,850 meters above sea level, has been operating since 1910.

In 2014 the Chuquicamata mine has produced copper as the main product of about 340.4kt of fine copper in cathode and copper concentrate,  production of gold produced from the mine is reached 757 t gold and silver 186.9 t.

New Top 5 Largest Open Pit Gold Mines In The World

Gold is a popular metal in the world because the characteristics, properties and composition. This metal has been a valuable and highly sought-after precious metal for coinage, jewelry, and other arts since long before the beginning of recorded history. The world consumption of new gold produced is about 50% in jewelry, 40% in investments, and 10% in industry.

Gold Ore occurs often in free elemental (native) form, as nuggets or grains, in rocks, in veins and in alluvial deposits. It occurs in a solid solution series with the native element silver (as electrum) and also naturally alloyed with copper and palladium. Less commonly, it occurs in minerals as gold compounds, often with tellurium (gold tellurides).In 2014 a total of 183,600 tonnes of gold have been mined in human history. This is equivalent to 9513 m3 of gold.

Many mining companies have exploited gold deposits to make the biggest gold mines in the world,  extracting gold ore requires large facilities. Open-pit mining, open-cut mining or opencast mining is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow. The result of using this technique is a huge visible scar on the earth surface

Ways Survey The Location Of Gold

Survey the location of the gold

The geology of metallic minerals as gold, silver and copper are often found in areas that have the ancient mountain. In addition to fertilize the soil, ancient mountain also produce a lot of metal deposition of gold, silver, copper and other metallic minerals.

In the process of finding an area that has the potential gold content, location survey process is very important. So that we can know the area contains a potential gold metal or not.
