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
Zimbabwe ASM
Zimbabwe’s famed Shamva Mining Centre (SMC) was conceived as a multi-functional service provider to respond to the stated needs of the small-scale gold miners in the Shamva area of Zimbabwe. The design and implementation of the SMC was based on providing a service for about 40 ASM mine sites.

Artisanal and Small-Scale Gold Mining Without
Artisanal and Small-Scale Gold Mining Without Mercury. In many countries, elemental mercury is used in artisanal and small-scale gold mining. Mercury is mixed with gold-containing materials, forming a mercury-gold amalgam which is then heated, vaporizing the mercury to obtain the gold. This process can be very dangerous and lead to significant
