摘要
通过一系列条件试验,最终确定"一粗一扫"浮选流程,选用轻柴油做捕收剂,粗选用量4000g/t,扫选1200g/t,仲辛醇做起泡剂,粗选用量400g/t,扫选200g/t,粗选矿浆浓度100g/L,充气量0.30 m3/(m2.min),得到最终粉煤灰产品产率65.54%,烧失量4.21%,达到Ⅰ级灰标准,粗选精碳产率19.85%,灰分58%,有一定的市场价值。
The rougher-scavenger flotation circuit was confirmed finally through a series of conditioning tests.Light diesel oil was confirmed for collector,the dosage is 4000g/t in rougher and 1200g/t in scavenger flotation.2-octanol was confirmed for the frother,the dosage is 400g/t in rougher and 200g/t in scavenger flotation.The pulp density was confirmed for 100g/L,aeration quantity 0.30 m3/m2·min,the experiments got the final fly ash product（productivity 65.54%,loss on ignition 4.21%） which reached the standards of tier one coal ash and the clean coal（productivity 19.85%,ash content 58%） which also had certain market value.
