The final step in the gold production process is refining. The gold recovered from the leaching and separation processes may contain impurities, and refining is necessary to achieve the desired purity level, typically 99.99%. 1). Smelting. Process: The recovered gold is mixed with fluxes (such as borax and soda ash) and heated in a furnace.

This process is suitable for mines with small production scale and high grade. For example, a gold concentrator processes typical iron-gold ore, with a processing capacity of 200 tons/day and a gold grade of 10 grams/ton. All ores are calcined in a rotary calciner. The calcined ore is transported into the percolation tank with a mining cart.
