The results showed that the better separation was achieved while using a new cationic surfactant DTL as de-sliming reagent, lime as activator for silicates, starch as depressant for iron minerals, oleic acid and dodecyl amine as collectors.

• 试验结果表明,采用添加新型阳离子表面活性剂DTL脱泥、石灰活化含硅矿物、淀粉抑制铁矿物、油酸及十二胺联合使用的新工艺方案,取得了良好的分选指标。
