A silicon and calciumbased phosphate ore contains low grade of phosphorite and high content of carbonate at a place in Saudi Arabia was dealed with doublereverse 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.
