浮选

After being oxidated for 34 h, and then the contents of Fe2+ in the 9K liquid solution with 4×10-4mol/ L xanthates, dithiophosphates and D-250 added inreased from 4.03 g/L to 4.64, 4.77 and 5.91g/L, respectively. After leaching for 35 d, the leaching rates of Zn are 92% and 61% respectively. It shows that the flotation reagents (xanthates, D-250) have great effect on the activity of bioleaching bacteria.

研究结果表明：添加4×10-4mol/L的丁基醚醇、乙基黄药、丁胺黑药，氧化34 h后，使 K液体培养基中的Fe2+质量浓度由4.03 g/L分别增加至4.64 g/L， 4.77 g/L和5.91 g/L；浸出35 d后，精矿中的浸出率分别为92%和61%，这进一步验证了浮选药剂对浸矿细菌活性的影响。

Analyzed the reason of high sulphur content in concentrated iron powder and studied the influence of milling fineness, PH value of pulp, used quantity of activator on rate of recovery of floatation adopting 307 ore sample as sample.

以307#矿样为试样，分析了铁精粉含硫高的原因，研究了磨矿细度、矿浆pH值、捕收剂及活化剂用量等对浮选回收率的影响。

And the thin degree of mineral is very thin. If want to achieve the rich purpose to collect the iron through rub the tailing again to separate the silicon and irons from the ore, it is very difficulty and the cost is too expensive.

由于浮选后的精矿品位不高，尾矿产生量大，其铁品位在43%左右，且原矿磨矿细度已经很细，如果想通过尾矿再磨，分离矿石中的硅和铁，达到富集铁的目的，难度很大，且成本不合算。

According to their flotation properties, the cleaning flotation test of the feel mixed by the coarse and fine rough cobalt梑earing sulfide concentrates was successfully carried out and the corresponding new cleaning flotw梥heet was recommended.
