摘要
本文研究了常压下用硫酸同时浸出会东闪锌矿与软锰矿,考察了浸出时间、温度、初始酸度、闪锌矿的初始粒径等对同时浸出的影响。并对实验结果作了讨论,推导出了同时浸出的经验动力学方程式。
This paper studies influence of temperature, the initial acid concentration, and the size of sphalerite particles on simultaneous leaching sphalerite yielded from HuiDong Mine and pyrolusite in sulfuric acid solutions at atmospheric pressure. Experiment results have been discussed. An empirical kinetics equation has been deduced. Actication energy of zinc and manganese is 57.28KJ/mol and 54.70RJ/mol respectively.
