Abstract: Tests indicate that the kinetics of leaching poorly-floated zinc–oxide–ore with ammonia comply with the shrinking un-reacted core model without solid product. By investigating the effects of ammonia concentration, temperature and size of ore on the leaching rate, it was suggested that the leaching of poorly-floated zinc-oxide-ore with ammonia is one of the first order reaction. Its activation energy is 11.1 kJ/mol, indicating that the external mass transfer was the rate controlling step.

摘要: 兰坪氧化锌矿氨浸的动力学实验表明,氧化锌矿的氨浸动力学遵从不生成固体产物层的未反应核缩减模型,即符合1–(1–a)1/3=[MkCn/(brd0)]t方程. 通过研究氨水的浓度、温度以及矿石粒度对难选氧化锌矿浸出速率的影响,发现氧化锌矿氨浸反应为一级反应,得到反应的活化能为11.1 kJ/mol,为边界层扩散控制.
