Process In Leaching Gold Mining

Jul 03, 2015 Of those methods, the ‘Cyanide Leaching Process’ (Cyanidation), is the method that is commonly used the most often to do this. As the name implies, the main component in the process is a sodium cyanide solution. This article will give a general overview about how this important, 120 year old gold mining process works.

Dec 27, 2017 Since the ores usually contain the gold and sometimes the silver in its elementary form, an oxidant is needed to bring about the dissolution of the precious metals. Normally, the oxygen resulting from aeration of the pulp is used for this purpose in the mining industry. (1) 4 Au + 8 CN- + O2 + 2 H2O → 4 [Au(CN)2]- + 4 OH-.

Apr 25, 2018 Heap leaching occurs after the mining and crushing of low-grade ores, usually in an opencast mine. High-grade ores and ores not amenable to cyanide leaching at coarse particle sizes require further processing to recover the gold values. These processing methods can include further grinding, concentration, pressure oxidation, and roasting, which is used to treat these ores to.
