At current gold prices this is worth about US$600. Both smelter treatment charges and oxidation or bio-leach costs are at least $200/t of concentrate and payables/recovery in the 90% range, so a minimum GSR for effective downstream processing is around 0.5. Clearly this is a function of gold price, but in the current gold …Web

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.Web

It has been estimated that grinding consumes up to 4% of global electrical energy and accounts for more than 50% of the total energy used in mining operations. In addition, more than 90% of the total energy supplied in beneficiation plants is dissipated as heat, kinetic energy, noise, and inefficient breakage of ores/raw material.Web

Data Overview. The study confirmed the nature of the mineralisation; the key results are presented in Table 1 and Table 2 and Figure 3. The overall conclusion was that the deposit is coarse gold-dominated (>40% of a 6.5 g/t Au grade), which indicates both gravity processing amenability and sampling challenges.Web
