碳酸锰矿硫酸浸出过程中锰及杂质元素的热力学行为初探

Rsearch on Thermodynamic Behaviour of Manganese and Impurity Element During the Process of Sulfuric Acid Leaching of Manganese Carbonate

根据国内碳酸锰矿中元素的赋存状态 ,通过热力学计算 ,探讨了碳酸锰矿硫酸浸出过程中锰及杂质元素热力学行为 ,提出了碳酸锰矿原料的选择要求及浸出过程中 pH值的控制原则。

According to the stand-by condition of the elements of manganese carbonate in China and through thermodynamics calculation, the paper investigates the thermodynamics behavior of manganese and impurity element during the process of sulfuric acid leaching of manganese carbonate. And it also puts forward the selection request of raw material of carbonic acid manganese ore and the control principles of pH value during the process of leaching.
