Economic feasibility of responsible smallscale gold mining

Artisanal mining (AM) activities are generally seen as a source of concern owing to their illegality and the environmental pollution that they cause, but in recent years it has been demonstrated that gold mining can be performed on a smallscale mining (SSM) in a responsible way outside of the artisanal dimension. A previous study by the same authors demonstrated how mineral resources and ...

[3] Evidence suggests that Nubia had sporadic access to gold nuggets during the Neolithic and Prehistoric Period. During the Bronze Age, sites in the Eastern Desert became a great source of goldmining for nomadic Nubians, who used "twohandmallets" and "grinding ore extraction ." By the Old Kingdom, the oval mallet was introduced for mining.

The Mining Process. 1. Mining Open Pit and Underground — To define the ore from the waste rock, samples are taken and assayed. Assay results are used to mark out areas of ore and waste rock, which are mined separately. Some of the harder areas require blasting to loosen the rock prior to excavation by hydraulic diggers.

Small samples of soil are taken on an expansive grid to identify parts per billion of gold. This method can also be used when geologists want to sample the top of bedrock, which can be 20 or 30 metres below the surface. A diagram based on pXRF sampling at Mitire Mining's Bateman's Project in NSW, showing areas of elevated silver.

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.
