Abstract：In order to decrease the moisture of flotation concentrate in Zhaogu NO.2 coal preparation plant,the authors added filter aids to the flotation system.Then the selection test and quantitative test were conducted.The selection test showed that the liquid filter aid was bet-ter than the solid filter aid in reducing the moisture and shortening the filtration time,so selected the liquid filter for quantitative test.The quantitative tests showed that the liquid filter aid TLT5140 was the best.The moisture could be reduced to 16.5% when the dosage was 80 g/ t (dry flotation concentrate).Based on the experimental results,the TLT5140 was selected finally for industrial test.Compared with the flotation concentrate which was produced without filter aids,the moisture of flotation concentrate which was treated by filter aid could be decreased by 3%.The unloading cycle of pressure filter was shortened by 50% as well.The filter aid decreased the moisture of flotation con-centrate,improved the production capacity of filtration equipment,met the customers? requirements.
