Phosphorite - Wikipedia

Deposits which contain phosphate in quantity and concentration which are economic to mine as ore for their phosphate content are not particularly common. The two main sources for phosphate are guano, formed from bird droppings, and rocks containing concentrations of the calcium phosphate mineral, apatite. As of 2006 , the US is the world's leading producer and exporter of phosphate fertilizers, accounting for about 37% of world P2O5 exports. As of December 2018 , the world's total economic demonst
