摘要:
贵州某磷矿石P2O5 、SiO2和MgO质量分数(w)分别为19.12%、24.18%和2.28%,属于中低品位硅钙质磷矿石. 采用胺类捕收剂AY和脂肪酸类捕收剂GJBW对该磷矿石进行浮选,考察磨矿细度和药剂制度对浮选的影响. 初步试验结果表明:采用双反浮选工艺,即粗选脱硅,扫选和精选同时脱硅、脱镁的开路试验流程,获得了P2O5含量为26.65%的磷精矿. 但磷精矿中P2O5回收率仅为58.27%,有待开展浮选工艺和药剂的优化试验.
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.
