Optimisation of gold recovery from small scale custom mills

2020-7-22  Gold small scale mining (SSM) and artisanal small scale gold mining (ASGM) was treated as illegal mining in many countries for a long time. This led to poor technology development in this area and till today many small scale miners use rudimental equipment. Some countries such as Mozambique, Ghana, Burkina Faso and Zimbabwe has legalised this sector and it is contributing immensely to their total gold production per year. Most of the methods used in SSM/ ASGM mining are gravity concentration methods followed by amalgamation. Amalgamation has been condemned in many countries due to mercury pollution but it has remained the primary method of gold extraction in many developing countries. This is due to the fact that amalgamation is inexpensive but inefficient. This has led to development of extraction methods such as the mercury free small scale gold extraction
