据陈小军,王晓玲报道:一座年生产规模为二千吨(原矿)的化学选矿新厂房去年十月在大吉山选矿厂落成,这是该矿在增强企业活力,提高经济效益上开辟新途径,开发新产品的结果。化学选矿综合回收是大吉山矿“七五”规划的重点工程项目之一。在这之前,该矿选厂每年产硫化矿二千吨,该硫化矿中主要含有铋、银、钨、铜、钼及硫等有用金属,但用过去的重—浮选矿工艺只能回收部分钼、铋且于精矿产出,仍有大量有用金属未能得到利用,为
According to Chen Xiaojun and Wang Xiaoling, a new chemical beneficiation plant with an annual production capacity of 2,000 tons (raw ore) was completed at the Dajishan Concentrator in October last year. This is a new way for the mine to open up new channels for enhancing the vitality of enterprises and increasing economic efficiency. The result of the new product. Chemical beneficiation comprehensive recovery is one of the key projects of Dayishan Mine “75” planning. Prior to this, the ore dressing plant produced 2,000 tons of sulphide ore each year. The sulphide ore mainly contains useful metals such as bismuth, silver, tungsten, copper, molybdenum and sulfur but can only be recovered by the heavy-flotation process in the past Some molybdenum, bismuth and concentrate in the output, there is still a large number of useful metals can not be utilized,
