我矿选矿厂由于在生产上采用了从锡精矿中浮选泡铋矿的措施,使铋的回收率提高了9.39％,锡精矿品位提高了7～8％;锡精矿含铋降低了2～3％,锡精矿质量由原来达不到部颁标准而上升到部颁标准的二类二级品。采取这一措施后,创造的经济价值相当于锡精矿再处理费用的二十四倍。为我矿开展增产节约,挖掘生产潜力,提高产品质量,降低生产成本做出了新成绩。
Due to the adoption of the flotation process of bismuth pyrite in tin concentrate, the recovery rate of bismuth increased by 9.39% and the grade of tin concentrate increased by 7 ~ 8%. The bismuth content in tin concentrate decreased 2 to 3%, the quality of tin concentrate from up to the ministerial standards rose to the ministerial standards of the second class two products. Taking this measure, the economic value created is equivalent to twenty-four times the cost of reprocessing tin concentrates. For my mine to increase production and save, tap the potential of production, improve product quality, reduce production costs made new achievements.
