浮选硫化铅锌老尾矿,由于菱锌矿和白铅矿中原生的闪锌矿和方铅矿深度氧化和物相变化,极难选别,这种老尾矿含锌2.9％,含铅0.75％(总的)。用硫化钠硫化后加黄药浮选的选矿结果不令人满意,作者提出一种方法,即将矿石在350～400℃下添加元素硫0.5～1.5％焙烧。焙烧产品然后用一般的方法加300克NaEX、500克Cu_2SO_4和80克松油(吨)浮
Flotation lead-zinc-zinc old tailings, due to the depth of calamine and galena in the calamine and lead ore depth oxidation and phase change, it is extremely difficult to choose, this old tailings containing zinc 2.9%, containing Lead 0.75% (total). Sulfur sulfide with sodium sulfide flotation beneficiation results are unsatisfactory, the authors propose a method that the ore is added at 350 ~ 400 ℃ elemental sulfur 0.5 to 1.5% roasting. The product is then roasted in the usual way by adding 300 grams of NaEX, 500 grams of Cu 2 SO 4 and 80 grams of pine oil (tons)
