METHOD AND SUBSTANCE FOR GOLD-CONTAINING CONCENTRATE

摘要

FIELD: electrochemical engineering. SUBSTANCE: method consists in selective dissolution in electrolyte of cementing and admixing metals contained in gold-containing concentrate and isolating these in series from electrolyzer. Implementation of the method is achieved when using as an electrolyte aqueous solution of alkali metal hydroxide in proportion 10-80 g per 0.8-1.5 L of water, or aqueous solution of sulfamic acid in proportion 10-150 g per 0.8- 1.5 L of water. EFFECT: provided environmental safety.
