硫化矿物中硫化银与自然银分离方法的研究

Study on the phase separation of silver sulfide in pyrites

文中针对硫化矿物中硫化银与自然银的浸取溶剂及分离方法进行了探讨。以8%巯基乙酸+3g/L单硫醇+2g/L丹宁酸+氨水溶液作为浸取剂,室温振荡3h,可作为硫化银与自然银分离的手段。该方法准确度高,精密度好,操作简便,结果令人满意。

The leaching solvents for the separation of silver sulfide and native silver were investigated in this test.At room temperature,the mixture of 8% thioglycollic acid,3g/L odd thio-alcohol,2g/L tannic acid and liquid ammonia can be used as the leaching solvent to separate silver sulfide and native silver in pyrites with vibrating for 3 hours.This separation method is convenient and with the features of high accuracy and good result.
