【摘要】 探讨了化学方法富集硫铁矿烧渣铁含量的可行性,以Na2S和NaOH对硫铁矿烧渣进行了处理,就药剂投放顺序、投药量及浸泡时间等因素对提高硫铁矿烧渣铁含量的影响进行了实验研究。硫铁矿烧渣的铁含量可从55.95%提高到64.79%。更多还原

【Abstract】 The feasibility of improving the content of iron in pyrite slag by chemical way was discussed.Pyrite slag was treated with Na2S and NaOH.The effects of the adding order of Na2S and NaOH,the amount of the chemicals and soak time on improving the content of iron in pyrite slag were studied.The iron content in pyrite slag can be improved from 55.95% to 64.79%.更多还原
