Gravity Concentration | GekkoGravity concentration is the separation of minerals based on differences in specific gravity. A gravity concentration process is designed to recover very high grades of valuable ore material into very small masses. The resurgence of gravity concentration in mining has come about due to its simplicity and low environmental.gravity seperation method concentration of ore,Concentration of Ores – Study Material for IIT JEE | askIITiansGravity Separation or Hydraulic Washing (Levigation). This method of concentration of the ore is based on the difference in specific gravities of the metallic ore and gangue particles. Generally metal ores are heavier than the gangue associated with them.

Artisanal and Small-Scale Gold Mining Without Mercury - EPA

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.
