Gold Smelting & Refining Process

Gold can be concentrated and recovered by applying different gold refining process methods and the final product has variable quality. In this way, it is necessary to have a better marketable product so that the incomes can be improved.

Gold Ore Processing | ScienceDirect

Gold roasting is a process, applicable to refractory ores and concentrates that contain sulfide sulfur, organic carbon, and potentially arsenic. Removal of these compounds is necessary to achieve high gold recovery (>90%) during cyanide leaching. Gold roasting is typically a metallurgical fluidized bed process.

Refractory Gold Processes - Mineral Processing & Metallurgy

Gold can be leached and extracted/recovered in several ways. Even if you gold is “refractory” in pyrite or arsenopyrite, you can still get much value from your ore/rock depending on the economics of capital and operating cost. The cheapest and fastest option is to simply grind and CIL the whole thing according the the process flowsheet here shown.

Gold mineral processing - Hatch Ltd

The worlds gold production has changed over the past 30 years. The exploration and discovery of large, free-milling gold deposits in major mining districts has declined. Mining companies face a difficult decision. Do they process large, low-grade deposits or look for smaller, often more complex ones in remote, often hard-to-reach locations?
