The Magic Effect of Lime in Mineral Processing JXSC

2021-2-20  The Magic Effect of Lime in Mineral Processing. Lime is widely used in mineral processing areas, like beneficiation processing, flotation processing, and leach processing. Also, lime can be used to raises the pH value, thus precipitating metals diluted in the water into tailing areas. And limestone is often used in the construction of tailing

Lime in Flotation and Recovery Processes Graymont

Lime is used extensively in the recovery of gold and silver. Ores, either run-of-mine, milled, autoclaved or roasted, are combined with lime and a cyanide solution. The cyanide dissolves the gold and silver. Lime maintains proper pH in the cyanide solution, keeping it in the liquid phase and preventing the formation of hydrogen cyanide gas and its loss into the atmosphere.

Lime use and functionality in sulphide mineral flotation

2019-11-1  At Silver Queen mine (Canada) a combined lime-starch-SO 2 conditioning scheme is used for copper flotation from the Pb/Zn sulphides (Bulatovic, 2007b). In the process, lime (1200 g/t) and starch (200 g/t) are used first, at pH 10.5–11.2, after which the pH is reduced to 5.5 with SO 2 (200 g/t) and the copper sulphide floated.
