Free FullText | Gravity Concentration in Artisanal Gold Mining MDPI

Worldwide there are over 43 million artisanal miners in virtually all developing countries extracting at least 30 different minerals. Gold, due to its increasing value, is the main mineral extracted by at least half of these miners. The large majority use amalgamation either as the final process to extract gold from gravity concentrates or from the whole ore. This latter method has been ...

Figure 4 CIL/ CIP Process Flow Schematic. Both CIP and CIL are continuous processes, where activated carbon is added to the ore/ water pulp. The first step in gold extraction is leaching the gold which turns gold in solid form to liquid with cyanide in the presence of oxygen. Next, the gold adsorbs to the activated carbon.

Step 5: Refining and Smelting. The eluate solution is pumped through electrowinning reactors where gold is plated onto cathode steel mesh or wool. (Electrowinning is a process of recovering metals from a solution by passing a current through it). The plated gold is then washed off and dried in cylinders called calciners, inside heated furnaces.

Step #9 Mine reclamation. After a few years, gold reserves in the mine will be exhausted. In the old days, the mine would be boarded up and abandoned. Today though, a reclamation project is done to try and return the land to its previous natural state as much as possible anyway. As you can see, the process of taking metal ore from the ...
