In sedimentary beds of phosphate rock, apatite occurs as a white or brownish earthy mass which must be detected by chemical tests. Because there is such a large range in composition of the various apatites, eight elements must be monitored (P, Al, Si, Na, K, Ca, Fe and Ti) for routine process control.
