Copper sulphide leaching in ferrous chloride medium with bacteria |
| abstract |
A method for leaching secondary and primary sulphides of copper in a ferrous chloride medium with iron-oxidising bacteria adapted from the crushing of the mineral from the mine, includes steps of: mixing the mineral from the crushing with concentrated sulphuric acid; transporting the material mixed with sulphuric acid by means of a belt; adding a liquid leaching solution at an intermediate point during transport on the belt, the solution consisting of: iron (II) sulphate to reduce the redox potential of the solution-mineral mixture to values less than 550 mV Ag/AgCl; iron (III) sulphate; bacteria and archaea of the mesophile- and thermophile-type belonging to the genera Acidithiobacillus, Leptospirillum and Sulfulobos; and sodium chloride to produce a chlorinated environment in solutions. The method also comprises the subsequent steps of: heaping the material on heap pads; during the resting step, injecting air warmed by a liquid/air exchange system; and leaching the heaped material. |
