摘要:
对宜昌丁东磷矿进行重介质选矿+正—反浮选试验与原矿直接进行正—反浮选试验研究,结果表明,分离密度为2.70时,只抛去17.35%的尾矿,量太少,仍需与正—反浮选联合使用,才能保证精矿品位P2O5 30%以上,回收率80%以上,MgO低于0.8%的磷精矿指标;而原矿直接进行正—反浮选流程(一粗一精一扫正浮选和一粗一扫反浮选),在不加温条件下,原矿P2O5 16.83%时,闭路试验可获得P2O5 31.49%,回收率83.75%,MgO 0.52%,选矿比为2.28的优良指标.可见,宜昌磷矿更适于采用直接正—反浮选流程,从而保证资源的经济、合理、有效利用.
Abstract:
Milling flow of middle and low grade phorsphorite ore in Yichang is studied.When the fluid medium has a separate density of 2.7 g/cm3 , 17.35% gangue is removed. Only using froth frotation after DMS, the high quality concentration(P2O5%>30%,recovery>80%,MgO%<0.8%) is gained. But the directreverse floatation processing is used directly. The high quality concentration(P2O5%=31.49%,recovery=83.75%,MgO%<0.52% is gained easily. It shows that technogical and economic date of directreverse floatation processing is better than that after dense medium separation (DMS) . Natural mineral resources can be exploited rationally and effectively.
