    phosphate minerals contain phosphorus and oxygen in a 14 ratio. Written as PO 4 this compound combines with other elements to form phosphates. The three mineral examples listed below are some of the more common members of this class. There are over 200 phosphates. The most common use of phosphate minerals is for fertilizer.
