某红柱石矿具有明显的斑状变晶结构。斑晶中含有石墨、石英、绢云母、黑云母、白云母、磁铁矿和电气石等矿物。试验前矿石用湿式强磁场磁选机处理,排除铁矿物,制取含红柱石、石英和白云母的试料,供浮选试验之用。试验使用离子交换水,在矿浆温度25～28℃,矿浆浓度18.5％下进行浮选试验。试验考察了阴离子型和阳离子型捕收剂(石油磺酸、环烷酸皂、氧化石腊皂、塔尔油、羟肟酸、油酸钠、十二烷基硫酸钠、C_5～c_9脂 Some andalusite has obvious macular degeneration. Plaque contains graphite, quartz, sericite, biotite, muscovite, magnetite and tourmaline and other minerals. Prior to the test, the ore was treated with a wet magnetic field magnetic separator to remove iron minerals and prepare samples containing andalusite, quartz and muscovite for flotation tests. The test used ion exchange water, and the flotation test was carried out at a pulp temperature of 25-28 ° C and a pulp concentration of 18.5%. Experimental study of the anionic and cationic collectors (petroleum sulfonic acid, naphthenic acid soap, paraffin soap, tar oil, hydroxamic acid, sodium oleate, sodium lauryl sulfate, C_5 ~ c_9 fat
