Most of the magmatic rocks contain accessory minerals.
It is also used to produce animal feed supplements, phosphoric acid, elemental phosphorous, and phosphate compounds for the chemical industry. Apatite is found in Myanmar (Burma), Brazil, India, Kenya, Madagascar, Norway, Sri Lanka, South Africa, Mexico, Canada and the United States. There are three minerals that actually contribute to apatite, which is the reason for the varied colors and shades of this stone.
