Refractory Gold SGS

SGS has developed a series of testing and mineralogy assessment protocols that allow us to determine the character of refractory gold and the mass balance between refractory and free-milling gold. Once the deportment or textural associations of the gold is determined and the mass balance known, flowsheet options are developed.

2004-7-1  The principal gold minerals that affect the processing of gold ores are native gold, electrum, Au-Ag tellurides, aurostibite, maldonite, and auricupride. In addition, submicroscopic (solid solution) gold, principally in arsenopyrite and pyrite, is also important. The main causes of refractory gold ores are submicroscopic gold, the Au-Ag tellurides, and very fine-grained gold (<10 µm) locked
