Cyanide Leaching Of Gold   Mine Engineer.Com

Cyanide Leaching Of Gold Mine Engineer.Com

Leaching gold from sulfide ores is difficult, at best. Generally, the recovery for cyanide leaching of sulfide or refractory ores is no better than 30%, which is not a worthwhile venture. The use of alkalies such as calcium oxide, will prevent the decomposition of cyanide in solution to form hydrogen cyanide gas.

Another recovery process is the use of iron exchanges. The uranium process is quite significant because of moving such a vast amounts of uranium. In the leaching process insoluble tetravalent uranium is oxidixed with hot H 2 SO 4 /Fe 3 + solution to soluble hexavalent uranium sulphate. The reaction is as below UO 2 + Fe 2 (SO 4)3 UO 2 SO 4 + 2FeSO 4

Simply put, leaching generally refers to the removal of a substance from a solid via a liquid extraction media. The desired component diffuses into the solvent from its natural solid form. Examples of leaching include the removal of sugar from sugar beets with hot water and the removal of nickel salts or gold from their natural solid beds with sulfuric acid solutions.

Processing Molybdenite Concentrate by an Acid Bake Leach

A process has been developed and piloted to reject copper, lead, iron, phosphorus, bismuth, antimony, elemental sulfur, and insol from molybdenite concentrate without decomposing the contained molybdenite and rhenium. The impure concentrate is first heated with concentrated sulfuric acid at 260 to 290 C for 1 hour. This bake not only oxidizes the contaminating sulfides, but also activates

In this operation, the two immiscible phases in contact are both liquid and so is a liquid liquid operation. The mass transfer of solute (liquid) takes place from feed solution to the solvent phase [2]. Extraction utilizes differences in the solubilities rather than differences in their volatilities.
