Oct 20, 2014· In addition to the retarding effects on the leaching process, the generated acid must also be continuously neutralised to prevent the formation of Hydrogen Cyanide (HCN) gas – increasing operating costs for the process. Lime is typically added to control and maintain the slurry pH to both assist reaction kinetics and suppress HCN formation.
Feb 04, 2016· I am also setting up a copper ore leaching system. I have ore that runs from 3% to 35% copper. The leaching tank holds about 225 pounds of ore - much of which is native copper in matrix. It also contains small amounts of silver. ... The more calcium in the form of Lime and magnesium in the form of dolomite you have in the ore, the more acid ...
Quicklime--both high calcium and dolomitic--enjoys its most extensive use as a flux in purifying steel in the electric arc furnace (EAF) and basic oxygen furnace (BOF).Lime is particularly effective in removing phosphorus, sulfur, and silica, and to a lesser extent, manganese. Lime also has important uses in secondary refining of steel and in the manufacture of steel products.

Copper Leaching Practices. For centuries small amounts of copper have been recovered from acid mine-drainage waters. In recent years, the expansion of copper-bearing waste dump leaching for copper recovery has established a technological basis that is rapidly converting the art of copper leaching into a science.
The goal of leaching is to 'push the reaction to the right' ie; consume the reactants to produce the gold complex in solution. Therefore to leach the gold out of the ore and into solution, cyanide, and oxygen must be added to the slurry. Lime is added to the grinding circuit to modify the pH of the slurry to
