摘　　要：沙特某地区钙硅质磷矿石含碳酸盐较高、有用矿物较低.试验通过双反浮选研究,获得精矿:P2O532.32%、产率35.81%、回收率67.64%的选矿指标,其工艺流程和药剂制度较简单,试验及生产易控制.A silicon and calcium-based phosphate ore contains low grade of phosphorite and high content of carbonate at a place in Saudi Arabia was dealed with double-reverse flotation methods to obtain the concentrate.The content of P2O5 is 32.32% in concentrate,yield and recovery are 35.81% and 67.64% respectively.This way has simpler flotation flows and reagent system,and easier to control the test and production condition.
