Amalgamation is a process were gold particles are incorporated into mercury to effect separation from associated sands. The process of amalgamation normally begins after gravity concentration, though in some cases mercury may be added during gravity concentration. Mercury is added to the gold concentrate and agitated

Metallurgy & Mineral Processing
1 Over the past 15 years, mine-to-mill studies have focused attention on the impact blast fragmentation has on concentrator throughput. Blasting provides the first opportunity for comminution – or size reduction. It is also a cheaper and more efficient process, compared to both crushing and grinding.

Crushing in Mineral Processing
In mineral processing or metallurgy, the first stage of comminution is crushing. Depending of the type of rock (geometallurgy) to be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing is used on hard and abrasive rocks by placing them between a high wear-resistant plate/surface.
