摘要
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。
It is a new technology to leach out gold in acidic solution (PH value: 1-2) with pyrolusite used as oxidant and ammonium (sodium) thiocyanate as leaching agent.In this way, the leaching percentage and velociy of gold and silver are high and the property of leaching agent remains stably without environmental pollution. In addition, the requirements for leaching gold and silver by this method are studied thoroughly.
