硫氰酸盐法从高铜硫化金矿中浸取金银的研究

Study on the Extraction of Gold From Copper-Rich Sulfide Ores by Thiocyanate Process

本文对含高钢硫化浮选精金矿，采用新的硫氰酸盐法浸取金银，对影响浸取金的因素进行了仔细的研究，并与传统的氰化法做了比较，结果表明此法对难处理的高铜金矿有较高的浸取率，浸取速度快，浸取剂性质稳定，基本上不污染环境，是一个很有前途的提金方法。

A new technology is studied in detail to leach out gold from copper-rich sulfide ores using thiocynate as leaching agent and pyrolusite as oxidant in acidic solution.The extraction rate and velocity of gold are high and the property of leaching agent remains stably without environmental pollution.In addition, this method has been compared with cyanide process systemtially.
