贵州某硅钙质磷矿岩的浮选试验研究
Experimental Study on the Flotation of Silicon -calcium Collophanite
摘要
Abstract
Double reverse flotation process on a middle and low grade silicon - calcium collophanite from Guizhou Province was adopted. The factors which had effects on the grade and recovery of P2 O5 were investigated, including grinding size, pH of slurry, dosages of collector. The experiment results showed that a phosphate concentrate of P2O5 31. 38% with a recovery of 86. 52% was obtained when using the process of twain roughing and once cleaning under the condition of the run -of - mine of P2O5 26. 04 % and grinding fineness of -0. 074mm 84. 28%.关键词
