Title: Optimization of Bioleaching Conditions for Yinshan Low-grade Complex Sulfide Ores
Abstract: To effectively utilize the low-grade complex copper sulfide ores in Yinshan Mine of Jiangxi Province,trial tests and an orthogonal test were performed using shake flasks to optimize the bioleaching conditions,including bioleaching strains,temperature,pH,rotational speed and pulp density.The results show that,leached with a combination of thermosulfidooxidans and acidithiobacillus caldus,the copper leaching rate can reach 72.3% under optimized conditions as: leaching temperature of 45 ℃,initial pH of 1.7,rotational speed of 190 r/min and pulp density of 10%.This study provides a theoretical basis for industrial application of bio-hydrometallurgy for low-grade complex copper sulfide ore in Yinshan Mine.
