絮凝剂复配在铝土矿浮选尾矿沉降中的应用研究
Experimental Research on the Flotation Tailing Sedimentation of Bauxite with Composite Flocculation
摘要
Abstract
In order to solve the problem of poor dewatering and high dosage of flocculation in flota-tion tailing sedimentation of bauxite in Henan , composite flocculation of TLT8626, PAM and AS3318 was used for tailing sedimentation experiment , and the effects of compound component and proportion were investigated .The results showed that the clear supernatant fluid could be obtained when PAM or AS3318 was used alone , but the settling velocities were slow with low dosage of floc-culants;TLT8626 could settle slurry quickly in low concentration , but the supernatant fluid was not clear enough .When the ratio of TLT8626 and PAM was 2:1 or 1:1 and the ratio of TLT8626 and AS3318 was 5:1 or 2:l within a total amount of 180 g/t, the same sedimentation effect as 240 g/t PAM could be obtained .The dosage reduced 60 g/t, almost 25%of the total , so the cost of disposing flotation tailing was cut down .Furthermore , the mechanism of the composite flocculation was investigated , indicating that the key of composite flocculation located at the proper match be -tween molecular weights and particle size .This paper filled the blank of composite flocculation used in tailing sedimentation , and developed a new method for tailing sedimentation at home and abroad .关键词
