Processing Refractory Gold Hydrometallurgy: Leaching in

Processing Refractory Gold is so hard! Low recovery is very common with refractory ores, in fact a 70% recovery could be considered good. Refractory ores are normally have either a high sulfide content that masks the gold preventing cyanide leaching of the gold, or high organic content that also block gold leaching (reabsorbs the gold), or it can have a high clay content that also soaks up the

Refractory Gold Technology

Sherritt’s gold process has several advantages over traditional roasting practice. The process has low sensitivity to the sulphur, antimony and lead content of the feed material, allowing increased gold recovery in the mill flotation circuits, and/or the direct treatment of ores. It has been proven effective in the treatment of feeds which have varied in composition from 0.1 to 20% As, and

Gold processing technology for viable mining

We have developed Rapid Oxidative Leach (ROL), a pre-treatment process that has already generated interesting results in the copper industry and now has its own development track for refractory gold. Your typical refractory ore contains tiny inclusions, or sub-microscopic gold, within a sulphide mineral matrix, requiring physical and chemical altering of the mineral matrix to liberate the gold
