研究了氧化亚铁硫杆菌炭 1#菌株在炭窑口硫铁矿和含铜硫铁矿上的氧化反应 ,测定了细菌在矿石上的附着量 ,建立了一个描述细菌生长和矿物溶浸的动力学模型 ,由实验数据及文献数据确定模型参数 ,采用龙格 -库塔法对模型进行数值求解。结果表明 ,模型计算值与实验数据吻合良好 :细菌对炭窑口硫铁矿的溶浸主要为直接作用 ,对含铜硫铁矿的溶浸主要为间接作用。 The oxidative reaction of strain # 1 of Thiobacillus ferrooxidans on Charcoal Karst pyrite and copper-bearing pyrite was studied. The amount of bacteria attached to the ore was measured. A bacterial growth and mineral leaching Kinetic model, the model parameters are determined by experimental data and literature data, and the model is numerically solved by Runge-Kutta method. The results show that the calculated values ​​are in good agreement with the experimental data. The leaching of pyrite from the charcoal kiln mouth by the bacteria is mainly direct, and the leaching of copper-bearing pyrite is mainly indirect.
