Artisanal and Small-Scale Gold Mining Without Mercury
This process is mostly used in large scale mining operations but has been increasingly adopted in small scale mining because of its high gold recovery rate and low cost. The best practices for stone leaching are a combination of pre-concentration and mill leaching, as they lead to the least amount of waste, a short processing time for miners, and high gold recoveries. First,

Processing, smelting and refining gold World Gold
The two gold refining methods most commonly employed to derive pure gold are: the Miller process and the Wohlwill process. The Miller process uses gaseous chlorine to extract impurities when gold is at melting point; impurities separate into a layer on the surface of the molten purified gold. The Miller process is rapid and simple, but it produces gold of only about 99.5 percent purity.

Mercury, a dangerous pollutant, is the preferred method employed by small-scale miners for gold recovery. Gold extraction using mercury is comprised of the following four stages: 1) amalgamation, 2) separation of amalgamation, 3) removal of excess mercury, and 4) burning of the remaining amalgam to produce a gold sponge. Mercury can be released into the environment at each stage, which makes

Gold processing Gold processing Mining and concentrating: The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then piled into heaps for

How “Small” Is Small-Scale Gold Mining?
Small-scale gold mining isn’t really that small in reality. Workers employ a variety of methods and mining techniques. They pan for gold, dredge rivers, manually dig up ground with shovels, work with hydraulic systems, use mechanized crushers, and often utilize large earth moving equipment. Small-scale mining is also altering the fragile ecosystems by unsustainable mercury amalgamation
The Gold Smelting Process Melting, Smelting & Refining
Most large scale gold miners send their ore to smelters with large equipment for the smelting process. Small scale miners still can do their own smelting using specialized kilns. Many people confuse gold smelting with melting. Whereas gold melting is simply heating gold to turn into a liquid form before forming gold bars, smelting is a more complex process that involves the removal of
