摘　　要：焦作市铝土矿储量极为丰富,但以低品位矿石为主,必须经过选矿富集,方可达到利用之目的。对不同类型的铝土矿进行了选矿可行性试验评价,铝土矿经过选矿处理后,所得精矿的质量有很大提高,其A/S提高近一倍,使铝土矿中的低品位矿石得到利用,充分发挥了矿产资源的经济效益和社会效益。The bauxite reserve tilized for aluminum metallurgy in Jiaozhuo is very rich, but most of it is low grade. So, it can be uonly after being enriched by mineral processing. This paper introduces the mineral processing feasibility of the low grade bauxite ore. After mineral processing, the ratio of Al2O3/SiO2 of bauxite concentrate can be improved by nearly one times. This technology makes good use of the low grade bauxite resources, and obtains more economic benefits and social benefits of the mineral resources.
