Review of gold extraction from ores ScienceDirect

Review Of Gold Extraction From Ores Sciencedirect

Oct 01, 1994 Firstly, in highly refractory ores, the gold can be locked up in the mineral matrix so that leach reagents are unable to reach it. Secondly, in complex ores, reactive minerals in the ore can consume the leach reagents in side reactions and there may be insufficient cyanide andor oxygen in the pulp to leach the gold.
