Gold cyanidation

Gold cyanidation. It is the most commonly used leaching process for gold extraction. Production of reagents for mineral processing to recover gold, copper, zinc and silver represents approximately 13% of cyanide consumption globally, with the remaining 87% of cyanide used in other industrial processes such as plastics, adhesives, and pesticides.

How Is Graphite Extracted? Sciencing

Apr 25, 2017Shaft mining is employed to reach the deepest ores. There are shafts or tunnels for miners and heavy equipment to move in and out. A different shaft is used for transportation of extracted ore and an air shaft for ventilation. Slope mining is done with slanted shafts that are not too deep and helps to extract ore that occurs parallel to the ground.

Uranium Mining, Processing, and Reclamation Uranium

Generally, orebodies are either vein type, massive, or tabular in shape, and both the shape and ore thickness influence the mining method used. Vein type orebodies usually dip steeply, and this steepness can be used during mining with the ore being allowed to fall to lower levels to an extraction accessway . Uranium orebodies are often narrow and irregular.
