基于新型抑制剂TH-3100的萤石与含钙脉石矿物浮选分离试验研究
Experimental study on flotation separation of fluorite and calcium-containing gangue minerals based on new inhibitor TH-3100
摘要
Abstract
The carboxylic acid-sulfonic acid-nonionic terpolymer TH-3100 is a non-toxic and fully biodegradable mac-romolecular polymer.It was used as an inhibitor for the flotation separation of fluorite,dolomite and calcite for the first time in this study.The effects of water glass,soluble starch,ethylenediamine tetramethylene phosphonic acid sodium and TH-3100 on the flotation behavior of fluorite,dolomite and calcite were compared and analyzed by single mineral flotation test.The results showed that TH-3100 showed strong inhibition and selectivity at low dosage.When the dosage of TH-3100 was 3 mg/L,the flotation recovery rates of fluorite,dolomite and calcite were 81.25%,5.31%and 12.53%,respectively.when the fluorite ore is CaF2 grade of 26.18%and CaCO3 grade of 20.84%,by the flotation process of one roughing,one scavenging and eight cleaning,and the fluorite concentrate with grade of 90.62%and recovery of 69.07%can be obtained.关键词
