Phosphate is a relatively low unit-value commodity. Therefore, most phosphate rock extraction operations tend to involve surface mining, large-volume extraction and reasonably low transport distances to major markets (Bartels & Gurr 1994). In comparison to many other mineral commodities, the demand for phosphate rock appears relatively predictable

Phosphate Rock. Table of Contents. Apatite, the most abundant crystalline phosphate mineral, is found in igneous rocks and probably is the primary origin of all other phosphates, whether mineral or organic. Its chemical formula may be expressed as Ca5 (Cl,F) (PO4)3. The chlorine may be replaced almost entirely by the fluorine.

Ninety percent of the phosphate rock reserves are located in just five countries: Morocco, China, South Africa, Jordan and the United States. The U.S., which has 25 years of phosphate rock reserves left, imports a substantial amount of phosphate rock from Morocco, which controls up to 85 percent of the remaining phosphate rock reserves.

Properties of Phosphate Rocks. Anhydrous phosphoric acid forms prismatic crystals, which readily deliquesce in the air. As ordinarily prepared, concentrated phosphoric acid is a clear, colorless, syrupy liquid (specific gravity, 1.83), which attacks most metals and bases, forming the corresponding phosphate salts.
