摘要
以河北某TFe品位60.60%、含硫4.04%的磁铁精矿为试验原料,采用反浮选工艺对其进行了脱硫试验研究。考察了矿浆pH值、活化剂用量、捕收剂种类及用量对该铁精矿脱硫的影响。结果显示,在矿浆pH值5.5,粗选CuSO_4用量100 g/t,捕收剂丁黄药和丁铵黑药的配比1:1且粗选添加量为300 g/t的条件下,经一次粗选、四次精选,最终将铁精矿中的硫含量降至0.64%,TFe品位提高至62.31%。
A magnetic concentrate from Hebei Province contains 60.60% total iron and 4.04% sulfur.In order to realize desulfurization of the iron concentrate,reverse flotation method was adopted.The influences of pulp pH value,the dosage of activating agent,the species and the dosage of collectors were investigated. The results showed that the suitable roughing conditions were 5.5 pulp pH value,100g/t CuSO4,and 300g/t butyl xanthate and ammonium butyl aerofloat with a mass ratio of 1:1.An iron concentrate with 62.31% iron grade and 0.64% sulfur was obtained after one roughing and four cleanings.
