摘要： 在硫酸体系中用两矿法工艺，研究了在超声波强化过程条件下同时浸出含砷金矿和锰银矿，以分解包含金、银的毒砂和氧化锰矿物. 实验表明，在锰银矿/金矿(质量比)=1:1.3、硫酸浓度0.57 mol/L、温度95℃、高频高功率超声波作用条件下，毒砂最终分解率可达84.9%. 而提高毒砂分解率正是提高金浸出率的重要条件.

Abstract: As-containing gold ore and Mn-containing silver ore were leached simultaneously in sulfuric acid solution. The process was intensified by ultrasonic wave to resolve FeAsS and MnO2. Experiments showed that under the conditions of ultrasonic wave, As-containing gold ore/Mn-containing silver ore=1:1.3, vitriol consistency of 0.57 mol/L, reaction temperature 95oC, the resolution rate of FeAsS was 84.9%. And increasing the decomposition rate of FeAsS is very important to achieving higher leaching rate of gold.
