用电积方法直接提取氰化液中金，是根据溶液中金氰络阴离子Ａｕ（ＣＮ）－２的沉积原理，在直流电场作用下，使金在阴极上析出。江西金山金矿山多年采用电积法提金新工艺，简化了工艺流程，提高了金的总回收率，减低了金成本３０％～３８％。该提金工艺值得金矿山推广应用。
The direct extraction of gold from the cyanide solution by electrowinning is based on the deposition principle of the gold cyanide anion Au (CN) -2 in the solution, and gold is precipitated on the cathode under the action of a direct current electric field. Jinshan Gold Mine in Jiangxi Province for many years by the electrowinning method of gold extraction process, simplifying the process and improve the total gold recovery rate, reducing the cost of gold 30% to 38%. The gold extraction process is worth promoting the use of gold mines.
