Concentration of Ore Definition, Types and Properties of Ore

There are numerous methods of concentration and the methods are chosen based on the properties of the ore. Hydraulic Washing This method concentrates the ore by passing it through an upward stream of water whereby all the lighter particles of gangue are separated from the heavier metal ore. This is a type of gravity separation. Magnetic Separation

Concentration of Gold Ores a Key to Reducing Mercury Use

2/8/2021· As an important first step along the way to eliminating mercury, concentrating avoids a worst practice called wholeoreamalgamation, where mercury is brought into contact with 100% or the ore and losses of mercury to the environment can be very high as high as 50 parts mercury for every part gold produced (more often ranging from 201 to 41).

2/8/2021· Concentration of Gold Ores a Key to Reducing Mercury Use in Artisanal and Small Scale Gold Mining. Posted 3rd June 2012 by Kevin Telmer. In artisanal gold mining, mercury is essentially used to concentrate the gold. It does this by bonding with the gold to form a heavy amalgam that is then easily separated from the other minerals.

Elemental gold has a specific gravity of 19.3, and typical ore has a specific gravity of about 2.6. All gravity concentration devices create movement between the gold and host rock particles in a manner to separate the heavy pieces from the lighter pieces of material. The prospectors gold pan is the most familiar gravity concentration device.
