Method for processing and purifying medical stone

The invention relates to the technical field of mineral processing, and particularly discloses a method for processing and purifying medical stone. According to the medical stone processing and purifying method, hydraulic separation, flotation separation and magnetic separation are adopted, the primary medical stone product is obtained firstly, most gangue minerals and impurities in the raw materials are removed, the subsequent chemical treatment amount is greatly reduced, and the production cost is saved; and heating and leaching with hydrochloric acid, and further removing Fe impurities to obtain high-quality medical stone powder. The method has the advantages of being economical, environmentally friendly, easy to implement and operate, high in product yield, high in product quality and the like, and high-valued recycling of the low-grade medical stone is achieved. 本发明涉及矿物加工技术领域，具体公开了一种麦饭石加工提纯的方法。本发明提供的麦饭石加工提纯方法，采用水力分选、浮选分选和磁选分选，先得到麦饭石初级产品，去除了原料中的绝大部分的脉石矿物和杂质，极大地减少了后续化学处理量，节约了生产成本；再采用盐酸加温浸出，进一步去除Fe杂质，得到高品质麦
