2020-1-20 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

Treatment of Refractory Gold Ores SpringerLink

Abstract. Problem ores that yield low (say less than 80%) gold recovery by cyanidation when “normally ground” are defined as refractory. The term, as well as the technical methods used to treat such ores, are relatively new. Rose and Newman’s very comprehensive book, The Metallurgy of Gold, does not even contain the term refractory in its ...

Classification of refractory ores. 1. Carbonaceous gold ore. There is organic carbon which can do‘Rob gold’in gold and silver ore, and it causes that gold is adsorbed in the cyanide solution, make ore difficult to cyanide and leach. Generally, we use roasting and chlorination pretreatment to destroy all or part carbon.
