中文摘要: 在均匀混合的间歇式反应器中用氧化亚铁硫杆菌分解难处理金矿,研究了不同粒度矿粒分解的动力学.结果表明,细菌在矿粒表面的吸附符合兰格穆尔等温吸附式,等温吸附常数KA不受粒度大小的影响,而单位质量矿粒的最大吸收量XAm随着粒度的增大而减小.建立了用于描述细菌生长和矿石分解的动力学方程式,其与试验数据能很好的吻合,矿石的初始粒度对吸附在矿粒表面的细菌的生长以及矿石的分解都有很大的影响.

Abstract:The kinetics of the bacterial dissolution of refractory gold-ore particles by Thiobacillus ferrooxindans was studied with different particles sizes in a well-mixed batch reactor. The bacterial dissolution kinetics with different particle size are studied. The adsorption data was well correlated by the Langmuir isotherm equation. The equilibrium constant KA in the Langmuir equation was independent of the particle size, whereas the maximum adsorption capacity per unit weight of the ore XAm increased with decreasing particle size. The kinetic models of growth of T. f and dissolution of ore were established, and they fitted the experiment data. The initial particle size has a great effect on the growth of T. f and dissolution of the ore.
