  • lime use on copper mining ladonatella.be

    In the mining industry, lime products are used to refine and condition metal ores and non-ferrous metals such as Copper, Zinc, Nickel, Gold, Silver and Aluminum. For this application, lime products are used in the froth flotation of Copper, Nickel and Zinc and are used in Gold and Silver processing to ensure proper pH in the leaching circuit.Lime use and functionality in sulphide mineral flotation,Nov 01, 2019· 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.

It is by far the most reused metal on the planet. In the U.S. nearly as much copper is recovered from recycled material as is produced from mining. Recycled copper makes up roughly half of the metal’s usage worldwide.
