云锡公司现已堆存的锡尾矿近××××万吨,锡金属约××万吨,平均锡品位0.17%左右,这是云锡公司重要资源之一. 由于世界锡的储量已逐渐贫乏,锡价不断上涨,开采锡尾矿,回收锡金属,是形势所趋,而且云锡当前尾矿库容不够,寻找又很困难,所以,开发尾矿更是迫切.尾矿粒细与铁矿物结合而难选,成本是开发尾矿中的一个突出问题.本文即根据尾矿之特征,而 Tin tin company has stockpiled tin tail near ×××× million tons of tin metal about × × 10,000 tons, the average tin grade of about 0.17%, which is one of the important resources of the company tin.As the world’s tin reserves have been Gradually poor, rising tin prices, the exploitation of tin tailings, tin metal recovery is the trend, and the tin tailings current capacity is not enough to find and very difficult, so the development of tailings is even more urgent. Tailings fine and Iron ore combined with difficult to choose, the cost is a prominent issue in the development of tailings.This paper is based on the characteristics of tailings, and
