摘　　要：为了解决煤炭发热量低、矸石伴生等带来的环境污染问题,达到煤矸石资源化利用、保护环境及绿色可持续发展的目的,本文探究了跳汰选矿对煤泥分选及后续浮选的影响,通过跳汰处理,煤泥浮选的碳含量增加,硫含量明显减少,并对影响跳汰过程的床层厚度和上升水量进行了试验,将跳汰后得到的轻矿物进行浮选,并对浮选后C、S的品位及回收率进行测定。实验结果表明,经跳汰处理后的煤泥碳、硫得到了初步的分离,调整浮选条件后,跳汰轻矿物浮选后产率可达到33.52%,C品位为21.15%,S品位4.5%。In order to solve the environmental pollution problems caused by low coal heat generation and gangue concomitant,and achieve coal gangue resource utilization,environmental protection and green sustainable development,this paper explores the influence of jigging beneficiation on coal slurry sorting and subsequent flotation,the carbon content of coal slurry flotation increases and sulfur content decreased significantly through jigging treatment,and the bed thickness and rising water volume that affect the jigging process were tested,and the light minerals obtained after jigging were flotation,and the grade and recovery of C and S after flotation were measured.The experimental results showed that the carbon and sulfur of the coal slurry treated by jigging were initially separated,and after adjusting the flotation conditions,the yield of light minerals flotation after jigging could reach 33.52%,with C grade of 21.15%and S grade of 4.5%.
