摘要：針對(duì)非洲多哥膠磷礦礦樣,采用擦洗—破碎—脫泥—磨礦—反浮選開(kāi)路工藝流程進(jìn)行試驗(yàn),獲得了優(yōu)異的選礦技術(shù)指標(biāo)。在磨礦礦漿質(zhì)量分?jǐn)?shù)為65%、磨礦細(xì)度為-0.074mm質(zhì)量分?jǐn)?shù)占66.85%的條件下,由P2O5品位19.33%、MgO質(zhì)量分?jǐn)?shù)0.45%、SiO2質(zhì)量分?jǐn)?shù)7.49%、R2O3質(zhì)量分?jǐn)?shù)4.66%的原礦,獲得了P2O5品位31.64%、MgO質(zhì)量分?jǐn)?shù)0.38%、SiO2質(zhì)量分?jǐn)?shù)2.66%、R2O3質(zhì)量分?jǐn)?shù)1.60%、P2O5回收率64.08%的磷精礦,總尾礦P2O5品位12.24%。磷精礦質(zhì)量達(dá)到了制取磷酸的要求。
