Some phosphate rock is used to make calcium phosphate nutritional supplements for animals.

Research on Tailings Water of Phosphate Concentration ...

A research on tailings water of phosphate concentration is carried out to determine whether the water can be send back to the flotation process. The settlement tests of tailings was conducted, and the water quality analysis of upper tater was performed. Finally, we used the mixed water with different proportion composed of tailings water and tap water for flotation tests. Phosphor Bronzes, or tin bronzes, are alloys containing copper, tin and phosphorous. The phosphor bronzes contain between 0.5 and 11% tin and 0.01 to 0.35 % phosphorous. The addition of tin increases the corrosion resistance and strength of the alloy. The phosphorous increases the wear resistance and stiffness of the alloy.
