我公司冶炼厂检修炼铜转炉、鼓风炉时拆换的废镁砖中含有相当数量的铜,但是自建厂以来一直作为工业垃圾堆放,仅有少部分磨成镁粉供修炉使用。据资料介绍,废镁砖中的铜可以采用浮选法回收,且浮选尾矿可用以制造硫酸镁。从消除污染,保护环境,增产节约出发,我们对冶炼厂堆积十余年的废镁砖,进行了回收其中铜及其他有价金属的研究,并组织了连续小规模生产。本文介绍,用浮选法可以除去大量硫酸
My company smelter repair copper smelters, blast furnace blast furnace when the replacement of waste magnesia contains a considerable amount of copper, but since the construction has been piled up as industrial waste, only a small part of ground into magnesium for repair furnace use. According to the information, the copper in waste magnesia brick can be recovered by flotation method, and flotation tailings can be used to make magnesium sulfate. Starting from eliminating pollution, protecting the environment and increasing production and saving, we studied the recovery of copper and other valuable metals from the smelting plant for more than ten years and organized the continuous small-scale production. This article describes the use of flotation method can remove large amounts of sulfuric acid
