On the average 0-12 lb. per ton of aerofloat and 0.03 lb. of the di-thio-phosphate are substituted for 0.1 lb. of xanthate. Since a high-grade concentrate is desired in order to keep smelting costs as low as possible, the circuit usually comprises two stages of cleaning. In most plants flotation is carried out in mechanically agitated machines.

A typical gold plant uses aqua-regia solution containing 2:1 ratio of HNO3 and HCI to digest the ores received from the mining process. The digestion process is needed to extract the gold from the ores. However, this digestion process will generate a huge amount of acidic wastewater. With 100,000 m³/day wastewater generated from the …
Gold room operations can be as simple as a single electrowinning cell and eluate tank, drying oven and smelting furnace. Or they can incorporate gravity-concentrate tabling, separate concentrate leaching, multiple electrowinning cells, cell-mud handling and filtration, and large-scale smelting operations. The complexity of the operation generally …
Gold is removed from the ore with a conventional carbon in pulp cyanidation circuit. Typical gold recoveries exceed 95 %. by David Michaud February 29, 2024 August 6, 2015 Categories Flowsheets & Flowcharts, Gold Extraction
