摘要
通过柱浸试验,研究了从杂卤石中浸出钾,考察了喷淋速度、矿石粒度、柱高等因素对钾浸出率的影响。结果表明,实际生产中,在满足经济效益前提下,应尽可能破碎矿石、降低浸出剂流速、增长渗滤路径,以充分提取矿石中的钾。
The leaching process of potassium from polyhalite is studied. Influence of flow velocity of solution, ore size, volume high on extraction of potassium has been experiment researched. The results show that small particle ore size, slow solution flow velocity amd long diffusion path have been required. Much more potassiumas can be leaching from the polyhalite .
