根据原矿性质的变化及选矿技术的发展,处理期北山砂锡矿的流程有必要进一步完善,使之更为合理,以便进一步提高选矿回收率。本文以研究结果为依据,提出合理的可行的工艺流程。 According to the change of the nature of ore and the development of beneficiation technology, the process of Beishan sand and tin mine during the treatment period needs to be further improved to make it more reasonable so as to further improve the recovery rate of beneficiation. Based on the research results, this paper puts forward a reasonable and feasible process flow.
