摘　　要：云南某细粒级锡石浮选流程处理的矿石具有锡铁致密共生、嵌布粒度细、含泥量高的特点,属于难处理矿石。采用药剂预先脱泥-锡石浮选工艺,筛选出高效脱泥药剂TN-1,有效降低了矿浆中-0.010 mm粒级含量,改善了浮选环境。通过添加脱泥药剂TN-1,浮选捕收剂用量下降了11.43%,锡石浮选精矿中锡品位提高了0.632个百分点,回收率提高了2.55个百分点。One fine-grained tin ore treated by flotation flow has the features that tin-iron tight symbiosis,fine dissemination size,high silt content,it belongs to refractory ore.The process that pre-desliming by agent-flotation of tin ore was adopted to screen out efficient desliming agent TN-1,the 0.010 mm size fraction content in ore pulp was decreased efficiently,the flotation environment was improved.The dosage of flotation collecting agent decreased by 11.43%,tin grade in tin ore flotation concentration increased by 0.632%,the recovery rate increased by 2.55%,because of the addition of desliming agent TN-1.
