Effect Of Lead Nitrate On Cyanidation Of Gold OrEffect of lead nitrate addition on cyanidation of Havran, Ovacık, Mastra LCu (low copper) and Mastra HCu (high copper) gold ores was investigated by laboratory tests at the Ovacik Gold Mine Metallurgy Laboratory. Leach tests were performed at optimum NaCN additions and pH values while different lead nitrate additions were applied.

Minerals | Free FullText | A Study of the Effect of ...The high solubility of copper sulphide minerals is an issue in the cyanidation of gold ores. The objective of this study was to quantify the effect of individual copper sulphide minerals on the Hunt process, which showed advantages over cyanidation. High purity djurleite, bornite and chalcopyrite, with a P70 of 70–74 microns, were mixed with fine quartz and gold powder (3–8 micron) to ...
Gold Metallurgy Leaching in Cyanicides · Cyanidation as applied to ordinary gold and silver ores is a relatively simple process. When cyanicides {cyanideconsuming elements) are encountered in small amounts in the treatment of such ores, the various schemes already discussed, such as use of a lead salt or wasting barren solution, can usually be resorted to and successful operation maintained.
