  • Gold cyanidation

    Gold cyanidation (also known as the cyanide process or the MacArthur-Forrest process) is a hydrometallurgical technique for extracting gold from low-grade ore by converting the gold to a water-soluble coordination complex It is the most commonly used leaching process for gold extraction...

  • Types of Coal Mining

    When a coal seam is too deep to efficiently mine the coal from the surface, underground mining techniques are used The underground method of coal mining currently utilizes two main techniques: room and pillar mining, and longwall mining 1 Room and pillar mining involves cutting a system of rooms within the coal seem...

  • Cyanide Leaching Of Gold

    It has been proven that the rate of dissolution of gold in cyanide solution is directly proportional to the amount of oxygen present Normal water will have 8-9 ppm dissolved oxygen present in it If this oxygen is used up by other reactions, it may be necessary to aerate the solution, inducing oxygen into it, to speed up the reaction...

  • Displacement reactions

    Displacement reactions are easily seen when a salt of the less reactive metal is in the solution During the reaction: the more reactive metal gradually disappears as it forms a solution the less ....

  • The Extraction of Iron

    The calcium silicate melts and runs down through the furnace to form a layer on top of the molten iron It can be tapped off from time to time as slag Slag is used in road making and as "slag cement" - a final ground slag which can be used in cement, often mixed with Portland cement...

  • Bioleaching

    Bioleaching is a part of microbial mining In microbial leaching or bioleaching metals can be extracted from large quantities of low grade ores This process has been used for centuries to recover copper form the drainage water of mines the role of microbes in the bioleaching came into notice some 40 years ago Mechanisms Involved in Bioleaching...

  • Mining Waste

    Annual generation of hard coal mining waste in 2001 accounted for 384 Mt and waste from ore mining, almost entirely tailings, accounted for 299 Mt Current percentage of mining waste use was relatively high and accounted for 910% of generated coal mining waste and 751% of ore mining and processing...
