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 mercury exposure and health risks.

The process of reducing mined ore for processing is known as 'comminution', which is defined as 'the action of reducing a material, especially a mineral ore, to minute particles or fragments'; this is normally achieved at mining operations through one or more stages of crushing and milling.. Early mining activities were labour intensive. Ore breakdown …
The purpose of the primary crusher is to reduce the ROM ore to a size amenable for feeding the secondary crusher or the SAG mill grinding circuit. The ratio of reduction through a primary crusher can be up to about 8:1. Feed: ROM up to 1.5 m. Product: -300mm (for transport) to -200mm (for SAG mill) Feed Rate:
