东鞍山烧结厂浮选车间投产二十多年来,虽然产量、质量都超过了设计水平,但精矿品位1978年仅达61.06％,远远不能满足钢铁生产的要求。为了提高浮选精矿品位,近几年作了不少试验研究工作,都未能取得十分满意的结果。为继续探索提高精矿品位的途径,挖掘现有浮选生产工艺的潜力, Although the output and quality of the Dongfanshan sintering plant flotation plant went into production over the past 20 years, the concentrate grade exceeded 61.06% in 1978, which far can not meet the requirements of steel production. In order to improve the quality of flotation concentrates, many experiments and studies have been done in recent years, and none of them has achieved satisfactory results. To continue to explore ways to improve the quality of concentrate, tap the potential of the existing flotation production process,
