autoclave pressure oxidation gold au c grinding mill china

autoclave pressure oxidation gold au c grinding mill china

Typical autoclave operating conditions for a refractory gold process are a . temperature of 190 to 230OC, and an oxygen over-pressure of 350 to 700 kPa (50 to 100 psi). The oxidation of sulphides are strongly exothermic reactions, and the pulp density of the feed to the autoclave is calculated based on the sulphide concentration in such a
