Mercury amalgamation is the method of choice to recover gold in artisanal and smallscale gold mining (ASGM). However, despite the low cost and simplicity of this method, the use of mercury presents serious health and environmental risks, as well as low efficiency in gold extraction. This study investigates the application of cyanide and thiosulphate leaching as alternatives to mercury ...

In some ores a large percentage of the gold occurs with the sulphides, which may only constitute a small proportion of the ore. Extremely fine grinding may be necessary to liberate this gold from the enclosing sulphides. In these cases, if the entire mill feed was entirely ground, the cost of the operation would be very high.

Thus, ore dust containing gold is lost to the environment during milling and unloading of the mill. Wet milling is normally used in direct smelting, but in this experiment dry milling was used for both methods for a thorough comparison. Dry milling likely resulted in a loss of a small amount of gold and thus biased the results in favor of the ...
