Optimisation of the mine closure process - ScienceDirect

Jan 01, 2006 · One of the more important tools for quantifying risk in mining is the Workplace Risk and Control or WRAC technique. The method requires a team of key personnel to generate a number of possible hazards or events with a process or piece of equipment and quantifying the likelihood or probability and the consequence of that event occurring.

The Mining Process – Waihi Gold

A slurry of ground ore, water and a weak cyanide solution is fed into large steel leach tanks where the gold and silver are dissolved. Following this leaching process the slurry passes through six adsorption tanks containing carbon granules which adsorb the gold and silver. This process removes 93% of the gold and 70% of the silver.

Mining and Beneficiation of Phosphate Ore | IntechOpen

1/8/2016 · The activation of apatite particles during dry milling may enhance the adsorption of reagents, which favors the recovery of apatite. However, active defects may serve as the sites for the adsorption of water and some very fine gangue particles on the apatite surfaces, causing apatite particles to be less responsive to flotation.
