The pretreatment of refractory gold ore is a complex chemical process. In addition to the oxidation of pyrite, some side reactions also occur. The phase changes of refractory gold ore before and after pretreatment are shown in Fig. 11. The main phases of refractory gold ore include quartz (SiO 2), pyrite (FeS 2), and dolomite (CaMg(CO 3) 2 ...

High-pressure oxidation comprises the oxidisation of sulphide/carbonaceous gold ore at high pressure and temperature. Temperatures exceeding 200 °C and oxygen pressures above 2200 kPa are used to attain complete oxidation of the gold-bearing ore. Reaction rates can be very fast, and the technology is widely-accepted.

The calcine has an acid reaction, and before it can be handled in contact with iron and steel, it must be neutralized. This is carried out in a preliming step in a 7- by 7-ft. turbo-agitator, which oxidizes the ferrous salts and precipitates the corrosive sulphates and chlorides present as hydrates.

The gold ore once mined is processed by separating the gold mineral from the crude matter holding it together. The ore is then pulverized using pressure to create very fine particles. The fine particles are then heated in a furnace to temperatures over 1,064 degrees Celsius, which is the melting point of gold.
