This is a Diamond Processing Chart as it was done in the 1950s. World demand and production of diamond both for gem and industrial purposes has increased nearly five-fold during the past 25 years. Improved mining and recovery methods together with the discovery and development of new fields has enabled mining operations to fill the growing demands.

The Consep Acacia is a complete process solution to maximise recovery of gold from gravity concentrates such as those generated from a Knelson Concentrator. The Consep Acacia typically achieves overall recoveries in excess of 95%, often over 98%. Most importantly the Consep Acacia maintains an unblemished installation success rate.
 South Africa and Russia together produce around 85% of world primary PGM supply.6  Deposits in Russia and North America have high palladium contents while deposits in South Africa and Zimbabwe are richer in platinum.  95% of the known world reserves are located in South Africa.7  33% of PGMs are produced as co-products of nickel mining.
gold from loaded carbon were developed, that the process came into widespread use for gold recovery from ore. These procedures allowed the carbon to be recycled for further gold recovery. Today, many options are available to the recovery plant designer and operator for the stripping of gold from carbon.

Historically, mercury was used extensively in placer gold mining in order to form mercury-gold amalgam with smaller gold particles, and thereby increase the gold recovery rates. Large-scale use of mercury stopped in the 1960s. However, mercury is still used in artisanal and small-scale gold mining (ASGM), often clandestine, gold prospecting.

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 ...
A Gravity Recoverable Gold Test (GRG) value of an ore sample provides an indication of the amenability of the ore sample to gravity concentration. The GRG testing scheme is based on progressive particle size reduction, which allows recovery of gold as liberated while minimizing over grinding.
