Cyanide leaching of the ore consistently resulted in low extraction of gold (49%) and silver (18%) confirming the refractory nature of the ore. Alkaline sulphide treatment of the ore under suitable conditions was shown to leach out up to 85% Sb, which remarkably improved the extraction of silver from lt; 18% up to 90% Ag in the subsequent cyanidation step.

Arsenic and Antimony Sulphide Minerals in Cyanidation. The effects of arsenic and antimony sulphide minerals on the extraction of gold from a synthetic ore consisting essentially of free gold and glass sand were investigated. The amount of mineral added in each test was such that the synthetic ore assayed 0.25% As or 0.25% Sb. Get Price

There are many tutorials that claim to offer methods of gold recovery such as quot;Cupellationquot;*. These processes are DANGEROUS and put the user at the risk of inhaling vaporized metals. No over the counter breather will protect you from these dangers; Only lab grade isolated breathing systems can protect against metal vapors.
The recovery of traces of gold and antimony from these ores is only interesting for waste products, as this does not cause losses in the recovery of the main metal. The processing of the second group of ores (2), usually requires changes in the flowsheet in order to ensure the recovery of both the gold and antimony fraction.

Refractory gold processes. These ores are naturally resistant to recovery by standard cyanidation and carbon adsorption processes. These refractory ores require pre treatment in order for cyanidation to be effective in recovery of the gold. A refractory ore generally
Antimony leaching during pretreatment The extent of gold extraction was determined to be 39% which tended to increase with increasing temperature and concentrations of The leaching behavior of antimony from the ore was evaluated Na2S and NaOH under the conditions tested. during the alkaline sulphide leach tests performed under different conditions (Figs. 3 and 4).
