这是一种新的提金方法。在酸性溶液(pH1～2)中,以软锰矿作为氧化剂,硫氰酸铵(钠)作为浸取剂,对金银有高的浸取率,快的浸取速度,浸取剂性质稳定,基本上不污染环境。本文对浸取金银的条件进行了比较详细的研究。
This is a new gold extraction method. In acidic solution (pH 1-2), pyrolusite as oxidant and ammonium thiocyanate (sodium) as leaching agent have high gold and silver leaching rate, fast leaching rate, stable leaching agent property, Basically do not pollute the environment. This article on the conditions of gold and silver leaching carried out a more detailed study.
