本文简要介绍了矿石性质。该矿锰铁磷共生关系密切,嵌布粒度细,用机械方法很难分离,但金属矿物和脉石的分离较容易。用机械方法进行粗选是必要的.文章着重地讨论了确定粗选流程的试验依据,为新建选矿厂推荐了经济合理的简单流程。 This article briefly describes the nature of the ore. The mine is closely related to the manganese, iron and phosphorus symbiosis, embedded fineness, mechanical separation is difficult, but the separation of metal minerals and gangue is easier. It is necessary to carry out the rough selection by mechanical method.This article focuses on the experimental basis for determining the crude selection process and recommends a simple and economical process for the new concentrator.
