含锡高泥尾矿预处理量化分析及其对微细粒锡石浮选性能的影响
Quantitative analysis of pretreatment for high-mud tin-bearing tailings and its effect on flotation performance of fine cassiterite
摘要
Abstract
To address the challenge of recovering micro-fine cassiterite from tin-containing high-mud tailings,drilling samples of high-mud tailings from the Gejiu area were selected as the research object to investigate the effects of different pretreatment processes on the flotation performance of cassiterite.Based on process mineralogy analysis,various pretreatment processes including hydrocyclone,spiral chute,flotation desliming(using No.2 oil and SPS),and high-speed centrifugation(200G,280G)were compared,and the comprehensive effects of each process were evaluated using quantitative radar map analysis.In flotation tests,the type and dosage of reagents were optimized according to the theory of fine particle flotation,and flotation closed-circuit tests were conducted on all pretreated ore samples.The results show that the 280G centrifuge exhibits the best performance for tailings pretreatment and tin-iron separation.The pretreatment processes significantly impact cassiterite flotation behavior.The surface properties of cassiterite are altered by the pretreatment processes.The slime coverage on cassiterite surfaces is reduced by hydrocyclone and centrifuge pretreatment,leading to the improvement of flotation performance.This study offers new process insights and technical support for the efficient recovery of fine cassiterite from high-mud,tin-containing tailings.关键词
