Gold's new golden moment - FLSmidth

Process low-grade stockpiles earlier for pre-treating refractory gold the main objective is to oxidise the pyrite and arsenopyrite to liberate gold. Initially the target is refractory gold-bearing iron sulphides where currently pre-treatment is the only solution to recover sulphide mineral matrix locked inside the gold. To this end FLSmidth has developed Rapid Oxidative Leach (ROL) a mechano-chemical pre-treatment process for refractory gold ores.

Refractory Gold Technology

Sherritt’s Refractory Gold Technology is used to recover gold from refractory sulphide feedstocks. Many gold ores and concentrates contain fine grained gold locked within sulphide minerals such as pyrite and/or arsenopyrite unavailable for recovery by conventional leaching. In Sherritt’s gold process the sulphide and arsenide minerals are completely oxidized by pressure oxidation thereby liberating the gold.

Recovery Refractory Resources - SGS

refractory gold ore is gold-containing ore that is resistant to recovery by direct cyanidation and carbon adsorption processes. More specifically it is an ore that has a gold recovery rate of less than 80% when direct cyanidation is applied to it. Dr Chris Fleming senior metallurgical consultant at SGS Minerals says: “In the

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 cyanide.
