起泡剂对浮选效果的影响

Effect of Frothing Agent on the Floatation Result

试验选用5种常用起泡剂对介休洗煤厂入浮煤泥进行了浮选试验,通过对比试验和初步优化试验,结果表明在浮精灰分为9 0%～9 5%的条件下,精煤产率应控制在80%左右,建议浮选药剂为:仲辛醇用量30g/t,煤油用量600g/t;或GF油用量100g/t,煤油用量1000g/t。

The floatation test of slime by using 5 forms frothing agent was conducted in Jiexiu Coal Preparation Plant. The result is shown that, cleaned coal yield is about 80% when cleaned coal ash content is under 90% ～95% condition through contrast test and primary optimum test. The frothing agent consumption is suggested that: secondary octanol 30 g/t, kerosene 600 g/t or GF oil 100 /t, kerosene 1000 g/t.
