Dec 03, 2019· Process of electrowinning of gold, also called electric extraction, is a process of recovering gold by desorption electrolysis of gold loaded carbon under high temperature and high pressure conditions. It is an important part in the gold cyanidation process. Why is this process widely used in mineral processing plants?

Feb 29, 2016· Gold recovery with sluices can vary depending on several factors. Fine gold losses can be minimized by cleaning up more frequently, reducing the speed of the slurry flow to around 0.50 to 0.80 m/s., and decreasing the feed size by performing a previous screening.
*Mining costs includes stockpile re-handle, LOM mining costs exclude pre-stripping. The LOM operating cost estimates for Blackwater peak in Phase 1 at $28.42/t, with economies of scale and driving down costs to C$23.30/t in Phase 2 and $15.13/t in Phase 3. Over the LOM, the Project has estimated average operating costs of C$17.65/t.
Gold bearing solution will then be pumped to a 240m3/hr carbon in column circuit comprising 6 counter current carbon contact tanks for adsorption onto carbon (Figure 5). Loaded carbon is then removed periodically reporting to the elution circuit for gold recovery and subsequent electrowinning and smelting to gold bullion (Dore).
The carbon is then generally subjected to a heated solution (200 deg to 250 deg F) of (1%) sodium hydroxide and (0.1%) cyanide and the gold is re-dissolved and removed from the carbon surface. At this point, the NaOH/CN solution is sent to electrowinning cells, where the gold is …
A cylindrical electrowinning cell employing a three-dimensional steel wool cathode has been used to investigate the effect of free cyanide concentration, pH, solution conductivity and base metal impurities on the electrowinning of gold from alkaline cyanide leach liquors containing up to 5 mg/l gold.
