Eco-friendly and economical extraction of gold from a ...

2020-12-1  Iodine–iodide leaching is an effective and environmentally friendly gold extraction method that is expected to replace cyanidation. However, as the price of iodine is relatively high, for the industrial application of iodine–iodide leaching, decreasing the required amount of iodine is important to reduce production costs.

Diagnostic Leaching in Refractory Ores Gold

2014-1-27  Abstract: The amenability of a refractory ore to the extraction of gold and silver by cyanide leaching was investigated. Diagnostic leaching tests were also performed to shed light on the refractory characteristics of ore. The leaching tests show that the ext raction of gold and silver is consistently low, i.e. ≤ 47% and ≤ 19.2%, respectively, over a leaching period of 24 h.
