conditions, elution (desorption) of gold from the carbon occurs. The main factor that makes desorption or stripping a simple process is the fact that gold will only adsorb onto carbon at low temperatures. If the temperature of a solution and carbon mixture is increased, the gold will readily desorb from the carbon into the solution. Temperature

Aug 01, 2017· 1. Introduction. The governing method for gold ore processing has been cyanide leaching since the late 19th century (Marsden and House, 2006).After decades of active development of the process for various types of ores and concentrates, there are several different hydrometallurgical flowsheets for cyanide leaching.
This is an excellent starting point to commence elution optimisation. Optimisation of the 125°C AARL elution circuit at a small high grade gold mine in PNG in 1996 increased the weekly stripping rate from 6 to 21 strips/week. This facility had been badly bottlenecking the rest of the plant as it regularly campaigned up to 30gpt Au and 200gpt Ag.
