Abstract

The possibility of concentrating gold in refractory gold-bearing arsenic ores from the Sukhoe deposit by decomposition with ammonium bifluoride and ammonium sulfate was investigated. Treatment of sulfide minerals with a mixture of ammonium bifluoride and ammonium sulfate increased the gold concentration by more than 700-fold, creating the prerequisites for its subsequent recovery. An approach to the quantitative determination of gold and arsenic by ²⁵²Cf-INAA was developed.

难选硫化矿石中微金和纳米金富集可能性的研究

研究了用二氟化铵和硫酸铵分解难选含金砷矿石富集金的可能性。用二氟化铵和硫酸铵的混合物处理硫化矿物，使金的浓度提高了700多倍，为随后的回收创造了先决条件。建立了用252Cf-INAA法定量测定金、砷的方法。
