1月15日,国土资源部公布了锰、铬、铝土矿、钨、钼、硫铁矿、石墨和石棉8个矿种的矿产资源合理开发利用“三率”最低指标要求,并责令现有生产矿山要在本指标要求发布之日后两年内达到本指标要求。根据公告,露天硫铁矿的开采回采率不能低于92%;地下硫铁矿中,煤系沉积硫铁矿的开采回采率不能低于65%,非煤系沉积硫铁矿的开采回采率不低于80%。煤系沉积硫铁矿的选矿回收率不能低于70%,非煤系沉积硫铁矿的选矿回收率不低于80%。多金属硫铁矿共伴生矿产品位达到一定程
January 15, Ministry of Land and Resources announced the manganese ore, chromium, bauxite, tungsten, molybdenum, pyrite, graphite and asbestos mineral resources, the rational development and utilization of “three rates” the minimum index requirements and The existing production mines shall be ordered to meet the requirements of this indicator within two years after the date of the issuance of this indicator. According to the announcement, open-pit pyrite mining recovery rate can not be less than 92%; underground pyrite, coal-bearing sedimentary pyrite mining recovery rate of not less than 65%, non-coal-based sedimentary pyrite mining recovery rate Not less than 80%. Coal-bearing sedimentary pyrite mineral processing recovery rate of not less than 70%, non-coal-based sedimentary pyrite mineral processing recovery of not less than 80%. Polymetallic pyrite together with mineral production reached a certain level
