摘要 The flotation behavior of Xixia andalusite was studied with different collectors.The tests were conducted with a pure andalusite sample in micro-flotation cell and then with an ore sample in a mechanical flotation cell.The surface charge was measured on pure andalusite sample and the isoelectric point(IEP) was found to be pH 5.2.Andalusite is floated with an amine collector above IEP where mineral surface is negatively charged.In contrast,an alkyl sulfonate collector(sodium dodecyl benzene sulfonate) is effective in the pH range where andalusite surface is positively charged.Furthermore,andalusite is floated with oleate in neutral and mildly alkaline pH values.55.3% Al2O3 is produced with 75.6% andalusite recovery when using the alkyl benzene sulfonate collector.Starch is found to be an effective depressant for gangue minerals in alkyl benzene sulfonate flotation.Moreover,slimes are found to have an adverse effect on the flotation of andalusite.Therefore,pretreatment by desliming and pre-float(to remove carbonaceous species) prior to andalusite flotation is necessary. 研究应用不同捕收剂时红柱石的浮选行为。采用西峡红柱石纯矿物进行微型浮选试验,利用红柱石矿石进行小型浮选试验,测定纯红柱石表面的电荷。结果表明,红柱石的等电点为pH5.2。在pH值高于等电点时,矿物表面带负电荷,可用胺类捕收剂浮选红柱石。相反,红柱石表面带正电荷,用烷基磺酸盐捕收剂(十二烷基苯磺酸钠)浮选红柱石比较有效。在中性和弱碱性pH范围时用油酸盐可以浮选红柱石。用烷基磺酸盐捕收剂时可以获得含55.3%Al2O3,红柱石回收率为75.6%的红柱石精矿。在用烷基磺酸盐捕收剂时,淀粉是脉石矿物的有效抑制剂。此外,试验发现矿泥对红柱石浮选有不利影响。因此,浮选前必须脱碳和脱泥。
