介绍了Metso型高速搅拌介质磨在印度塔斯马尼亚铜矿和澳大利亚塞兰加铜矿中的应用。该搅拌磨用于铜粗精矿的再磨 ,由于再磨后铜矿物单体解离度提高及不用铁磨矿介质 ,改善了浮选矿浆电化学条件 ,因而最终铜精矿铜品位和回收率提高。同时 ,该搅拌磨还具有占地面积小 ,基本投资少和操作费用低等优点。
The application of Metso-type high-speed stirring medium mill in Tasmania copper mine in India and Seranga copper mine in Australia is introduced. The agitating mill is used for the regrinding of the crude copper concentrate. Due to the improvement of the dissociation degree of the copper minerals after the regrind and the absence of iron grinding media, the electrochemistry conditions of the flotation pulp are improved, so that the copper grade and Recovery rate increased. At the same time, the mill also has the advantages of small footprint, low capital investment and low operating costs.
