Placer Gold Mining

Placer deposit or placer is an accumulation of the precious minerals formed by the separation of gravity during the sedimentation process that naturally separate due to gravity and assisted the movement of a liquid medium, solid and gas / air. And placer mining is a very important source of potential resources of gold mining. Geologists frequently mention that the placer deposits Alochton. Density concentrations of heavy minerals is dependent on the level of freedom from the source, specific gravity, chemical resistance to weathering duration and mechanism. These types of deposits have been formed in all geologic time, but most of the Tertiary and the present age, is largely the reserve is small and often clustered in a short time because of an erosion. Most of these deposits have low levels of mineral ores but can be mined because of particle-free, easy to work with without destruction; where separation can use a semi-mobile and relatively inexpensive. Mining usually by dredging, which is the cheapest method of mining.

Mining Processing Operation

After the stage of preliminary exploration is known that the existing reserves have a good prospect with a review of knowledge or more accurate data regarding the depth, thickness, slope, and the spread of reserves in 3-Dimensions (length-width-thick) as well as data on the strength of rock sampling, groundwater conditions, and the spread of the structure, width and slope mines then conducted an exploratory stage in detail or commonly referred to as the exploitation of an activity carried out either in a simple (manual) or mechanical, including excavation, parsing, loading and transportation of minerals. Several phases of mining activities in outline are:

Creating A Simple Mapping of Land Gold

In any mining operation  or an exploration of mineral ore, it is very important to do a draft mapping activities  in the surrounding area will  be an exploration.where the mapping is very important in order to reduce risk and support the exploration  plan.

Because, basically, mapping activities affect the continuity of exploration. With this mapping, we can see the beginning of  the geological conditions of the working area and can see the potential resource deposits of the mineral deposits in areas that will be held exploration activities.

This mapping is usually done at the beginning of  the exploration  activities. The first step is usually done in a mapping can be done by doing an analysis through a photo presentation  by air or by using a satellite, where the presence of  the review  through the  air we can see the geographic structure and local conditions and our land that will be held survey field.

     

SILVER

Metallic silver is formed and used in conjunction with gold, with white color. this metal has the elements a little harder than gold and is very soft and supple, defeated only by gold and perhaps palladium. Pure silver has a thermal conductivity or heat and electricity are very high among all metals and has a very small contact resistance. This element is very stable in pure air and water, but immediately tarnished when exposed to ozone, hydrogen sulfide or air containing sulfur. benefits resulting from too many silver metal, besides used as accessory equipment and furnishings. Silver is also an important element of the compound in photography, because of their unique optical and about 30% of industrial consumption of silver is used for this field. Silver alloys are also used as a substitute for the artificial tooth, or a mixture of electronic materials

Location Of Gold Deposits Eluvial Placers

 Eluvial ore deposits are those such as tungsten and gold placer deposits formed by settling and enriched by the winnowing or removal of lower density materials. Eluvial gold placed by the process of gravity on the surface of the hill, up and flat-lying areas. Particles of minerals or ore-forming mineral deposit type is deposited on top of a rocky hillside source. In some areas found in eluvial placer with ingredients that create economic value accumulated in the pockets of bedrock surface. Rainfall helps to bring the material surface, or floating, downslope. Eluvial deposits consist of fragments of rock and soil which are not consolidated lying on the surface. It is derived from coral quartz and other minerals deposits (supergene, reef quartz and layer) located at the top. Transported material contain gold deposits also form on the surface of the slope of the hill where the concentrated on changes in gradients, like, bottom of the hill. Deposits are usually located near the eluvial placer, which is an irregular surface on the hillside below the mineral resource.
