云南某低品位硅钙质磷矿石矿物学研究及生产应用
|
摘要
对云南滇池周边堆存的低品位硅钙质磷矿进行矿物学研究,查清矿石的化学组分、矿物组成、嵌布粒度、解离性等特征,结合云南磷化集团安宁矿业分公司200万t/a浮选装置生产工艺流程为配矿提供依据,最终获得了P_2O_5品位29.00%～30.00%、MgO质量分数0.89%～1.00%、产率65%～68%、P_2O_5回收率86%～88%的磷精矿。
The mineralogical study of low-grade silica-calcareous phosphate deposits around Dianchi Lake in Yunnan was conducted to find out the chemical composition,mineral composition,dissemination size,liberation property and other characteristics of the ores in combination with providing a basis for ore blending in a 2 Mt/a flotation plant of Yunnan Phosphate Chemical Group,Anning Mining Branch,eventually obtaining the separation indexes of P_2O_5 grade 29.00% ～30.00%、MgO grade 0.89%～1.00%,yield 65%～68% and P_2O_5 recovery rate 86%～88%.
