铁山垅钨矿为解决锡精矿质量不高的问题,自1997年起,投资20多万元建成了钨锡分选生产车间,历经3年多的工业生产实践,已生产出合格的锡精矿,每年可为企业增效30万元。 铁山垅钨矿主产品“铁山牌”黑钨精矿,曾连续3次荣获国家银质奖,附产品铜、铋、钼、锌等产品质量均达部颁标准或用户要求,唯独矿物锡的回收因处理工艺不合理,难以获得合格精矿,只能作钨锡中
Tieshan 垅 tungsten mine to solve the problem of tin concentrate quality is not high, since 1997, more than 200,000 yuan investment to build a tungsten-tin sorting production workshop, after three years of industrial practice, has produced qualified tin Concentrate, annual synergies for enterprises 300,000 yuan. Tieshan 垅 tungsten ore main products, “Tieshan” black tungsten concentrate, has won three consecutive national silver medal, with products such as copper, bismuth, molybdenum, zinc and other product quality reached the ministerial standards or user requirements, the only Mineral tin recovery due to unreasonable treatment process, it is difficult to obtain qualified concentrate, only for the Tungsten Tin
