中低品位硅钙质磷矿石双反浮选的探索试验
Exploratory Testing of Double-Reverse Flotation for a Middle-Low Grade Calcareous-Siliceous Phosphate
摘要
Abstract
The mass fractions (w) of phosphorus pentoxide,silicon dioxide and magnesium oxide of a middle-low grade-calcareous siliceous phosphate ore in Guizhou province are 19.12%,24.18% and 2.28%, respectively. In this study,the effects of the grinding fineness and the reagents applied in the flotation were investigated by using the amide collector AY and fatty acids collector GJBW. The preliminary results showed that the concentrate with phosphorus pentoxide mass fraction of 26.65% was obtained by using double reverse flotation process,namely the open circuit test procedure with removing the silicon by roughing and removing the silicon and magnesium by scavenging and concentration,but the recovery of phosphorus pentoxide is only 58.27%. So,the optimization test of floatation technology and reagent is expected to carry out in the future.关键词
