上海铁合金厂在生产炭素铬铁产品的熔炼过程中,产生大量的炭素铬渣。由于炭素铬渣块度大,铬铁难于分离,故作废渣全部抛弃或作填沟铺路用,污染环境,浪费资源。该厂于1986年开始,采用破碎—跳汰选矿法从炭素铬渣中分离铬铁试验获得成功。并于1987年建成年处理炭素铬渣1.5万吨生 Shanghai ferroalloy plant in the production of carbon ferrochromium product smelting process, resulting in a large amount of carbon chromium residue. Due to the large size of carbon residue, ferrochrome is difficult to separate, so all the waste residue for ditches or paving for use, polluting the environment, a waste of resources. The plant started in 1986, the use of crushing - jig beneficiation method from the separation of ferrochrome carbon chromium slag test success. And in 1987 completed the processing of carbon chromium slag 15,000 tons students
