摘要:
为充分利用矿产资源,对某磁选尾矿进行回收磷灰石浮选试验,通过一次一因素条件试验和正交试验分析研究了磨矿细度、粗选质量分数、药剂用量等因素对浮选的影响.结果表明:对P2O5品位为4.21%的磁选尾矿,磨矿细度-0.074 mm含量为45%时,经一次粗选二次精选,中矿循序返回,可以获得磷精矿P2O5品位36.19%,回收率90.41%的选矿指标.最终的磷精矿达到HG/T 2673-1955《酸法加工磷肥用磷矿》一类专业标准,使磷灰石得到有效的回收利用.
Abstract:
To make the best use of the mineral resource, the flotation tests were conducted on a certain magic tailings, reclaiming phosphorites. By having done the singleorder singlefactor conditional tests and analysis on the crossing tests, the factors which worked on the flotation were researched, such as grinding fineness, roughing pulp thickness and reagent dosage. The results showed that for the tailings which P2O5 grade was 4.21%, grinding fineness was 45% for minus 0.074 mm, worked by one roughing, two cleanings and the middlings returned in turn, the concentrate which P2O5 grade was 36.19%, recovery was 90.41% was obtained. The concentrate met the standards of HG/T 2673-1955 “Acid methods processing for phosphorus fertilizer”, and the phosphorite was reclaimed availably.
