一、概述 我矿根据改造细泥工艺流程的需要,1979年购买了一台φ600毫米平环湿式强磁场磁选机。1982年4月安装投入生产,至今巳两年多。运转正常,指标良好,对提高我矿钨细泥精矿质量、加强综合回收、提高经济效益等都起到良好的作用。 给入磁选机的原料,主要是用“离心选矿机——浮选”处理细泥原矿获得的精矿和-60目重选毛精矿。品位含Wo_3为38—52％,生产的细泥精矿为两部分,一部分大于65％WO_3直接销售,一部分含WO_335～40％,
First, an overview of mine mine fine mud according to the transformation process needs, in 1979 bought a φ600 mm flat ring wet magnetic separator. April 1982 installation put into production, it has been more than two years. Normal operation, the index is good, to improve the quality of mine ore fine mud concentrate, strengthen comprehensive recovery, improve economic efficiency and so play a good role. The raw materials fed to the magnetic separator are mainly the concentrate obtained from the treatment of fine mud ore with “Centrifuge Concentrator - Flotation” and the concentrate of -60 mesh re-election. Grade Wo_3 is 38-52%, fine silt concentrate produced in two parts, a part of more than 65% of the direct sales of WO_3, some containing WO_335 ~ 40%
