Cyanide In Grinding Circuit

Cyanide is usually added in the freshly aerated solution pumped to the grinding circuit, although sometimes blocks of cyanide may be suspended in baskets in a dissolving circuit to remedy some local trouble.Gold Metallurgy & Leaching in Cyanicides,Direct Leaching in Grinding Circuit Among the minerals containing iron in the ferrous state are pyrrhotite, chlorite, cummingtonite (an iron-magnesium amphibole), and a dolomitie carbonate. Some of these carry as much as 30 per cent iron.Cyanidation in Grinding Circuit: Evaluation of Leaching,,"In gold processing plants, it is common to start gold cyanidation in the grinding circuit by simple cyanide addition or as a result of recycling residual cyanide. In such cases, advantages such as a decrease in gold lockup and reduced leach time have been noticed.
