几年来我厂根据矿石特点,不断强化工艺流程,提高了选矿指标。其效果是:改革闭路破碎流程,使破碎最终产品粒度由62—0毫米降至33—0毫米,球磨机生产能力提高4.5吨/台时;增加磁滑轮干式磁选,抛弃了产率为15%,铁品位5.71%、铜品位0.037%、钻品位0.002%的废石;用浮选机取替浮选柱,铜回收率提高3%以上;增加铁的精选作业,使铁精矿品位由63～64%提高到66%以上,同时降低铁精矿滤饼含水2%左右。
Over the past few years I plant characteristics according to ore, and constantly strengthen the process and improve the dressing index. The effect is: the reform closed-circuit crushing process, so that the final grain size crushing dropped from 62-0 mm to 33-0 mm, the ball mill production capacity increased 4.5 tons / set; increase the magnetic pulley dry magnetic separation, abandoned the yield of 15 %, Iron grade 5.71%, copper grade 0.037%, 0.002% of the diamond grade of waste rock; flotation column instead of flotation column, the copper recovery rate increased by 3%; increase iron selection operations, so that the iron concentrate grade From 63 ~ 64% to 66%, while reducing iron ore concentrate filter about 2% water.
