| Abstract: | 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. |
