Effect of Ultrasonic Wave on Simultaneous Leaching of Mn-containing Silver Ore and As-containing Gold Ore
|
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.
