摘要
锡石性脆,在碎磨过程中容易泥化,重选工艺难以有效回收微细粒锡石,浮选虽是锡石细泥回收的首选工艺,但现阶段的浮选效果并不理想。针对微细粒锡石浮选这一难题,概述了微细粒锡石浮选捕收剂、抑制剂的种类及其特点和应用情况,介绍了锡石捕收剂在浮选中存在的问题,指出了开发新型药剂、研制组合药剂及降低药剂成本的重要性,以期能够寻找到真正意义上的高效、低毒、低成本的锡石浮选药剂。
Cassiterite is easy to slime in the grinding process due to its brittle,the efficiently recovery of micro-fine cassiterite was difficult to achieve by gravity separation. Although flotation is the preferred technology for the recovery of cassiterite slime,the flotation result is not satisfactory at present. In view of the current situation of micro-fine cassiterite,the types,characteristics and applications of collector and inhibitor were summarized. Problems of cassiterite collectors in flotation were introduced,and the importance of developing new reagents,developing composite reagents and reducing the cost of reagents were pointed out in order to find the flotation reagents with high efficiency,low toxicity and low cost in a real sense.
