摘要: 为使广东某硫铁矿生产-3 mm产品过程中产生的矿泥得到高效利用,采用2台φ400 mm×4 000 mm旋流-静态微泡浮选柱在现场对该矿泥进行了1粗1精柱式浮选半工业试验。首先通过条件试验确定了合适的处理量、药剂制度以及浮选柱中矿循环泵压力,然后进行72 h连续运转,获得了硫精矿硫品位为48.46%、硫回收率为93.71%的良好指标。与现场采用浮选机的选别指标相比,硫回收率提高了约13个百分点。

Abstract: In order to effectively utilize the slime produced in the course of producing -3 mm production in a pyrite concentrator from Guangdong province, carried out the pilot test of once roughing once cleaning column flotation by two φ400 mm×4 000 mm cyclone static micro-bubble flotation columns.Suitable handling capacity, reagent system and circulating pump pressure of flotation column were determined by conditions test.After 72 h continous production, the S concentrate with 48.46% grade, 93.71% recovery was achineved, comparing to the spot flotation machine, the S recovery increased by 13 percentage ponits.
