Excuse me, what happened to cyanide gold extraction?

Cyanidation is still the main method to extract gold at home and abroad. Cyanidation is enduring for a long time, mainly because of its simple process and low cost. Cyanidation will be the main method to extract gold for a long time to come.

A process for directly electrolyzing and extracting precious metals such as gold from cyanide solution is characterized in that a special electrolytic cell is used for electrolysis, and the process parameters are: solution flow rate: 15- 150 L/min, and current density: 500-65438+. This technology has low cost and is suitable for industrialized students.

Another production process for extracting gold concentrate from gold-bearing cyanide residue includes desliming and shaking table. The cyanide residue containing gold 1.5-2g per ton is recovered by gravity separation, and the recovery rate is above 70-80%. Simple process, high recovery rate and good economic benefit.
