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, accou

phosphate mineral Description, Uses,Facts Britannica

Phosphate mineral, any of a group of naturally occurring inorganic salts of phosphoric acid. Phosphates can be grouped as: primary phosphates that have crystallized from a liquid; secondary phosphates formed by the alteration of primary phosphates; and rock phosphates formed from phosphorous-bearing organic material.

Mining The Phosphate Risk

The mining process in Florida begins with a field study to determine the location and density of the phosphate deposits. Information like the location, size, and shape of the ore is determined to focus the mining effort. Hundreds of boreholes are drilled and thousands of core samples studied and tested to gather information about the ore-body.

OverviewChemical propertiesProductionEcologySee alsoExternal links

In chemistry, a phosphate is an anion, salt, functional group or ester derived from a phosphoric acid. It most commonly means orthophosphate, a derivative of orthophosphoric acid H 3PO 4. The phosphate or orthophosphate ion [PO 4] is derived from phosphoric acid by the removal of three protonsH . Removal of one or two protons gives the dihydrogen phosphate ion [H 2PO 4] and the hydrogen phosphate ion [HPO 4] ion, respectively. These names are also used for salt

Beneficiation Wikipedia

In the mining industry or extractive metallurgy, beneficiation is any process that improves (benefits) the economic value of the ore by removing the gangue minerals, which results in a higher grade product (concentrate) and a waste stream ().There are many different types of beneficiation, with each step furthering the concentration of the original ore.
