Leaching Guide of Refractory Gold Ore cnlitereagent
28/02/2020· 1.What Is Refractory Gold Ore? With the development of beneficiation technology, the definition of refractory gold ore is changing. Generally speaking, refractory gold ore in leaching field is a kind of ore whose leaching rate of gold is less than 80% when directly processed by cyanidation after find grinding. 2.Why Gold Ore Is Refractory?

Refractory Gold Ore Treatment Methods
14/07/2016· List Gold Refractory Process Methods. Where gold is associated with arsenic, antimony, tellurium, and certain other minerals, it is often only partly soluble in cyanide solution. The difficulty is usually more of a physical than a chemical one but special methods of treatment may be required.
Refractory Gold Technology
Sherritts 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 Sherritts gold process, the sulphide and arsenide minerals are completely oxidized by pressure oxidation,
