Phosphate - Wikipedia

The phosphate ion is a polyatomic ion with the empirical formula (PO 4) 3− and a molar mass of 94.97 g/mol. It consists of one central phosphorus atom surrounded by four oxygen atoms in a tetrahedral arrangement. The phosphate ion carries a −3 formal charge and is the conjugate base of the hydrogen phosphate ion, H(PO 4) 2−, which is the conjugate base of H

The phosphate mining industry employed 2,200 people. The value of phosphate rock mined was US$2.2 billion. As of 2015, there are 10 active phosphate mines in four states: Florida, North Carolina, Idaho, and Utah. The eastern phosphate deposits are mined from open pits. The western deposits are mined from both surface and underground mines.

Phosphate | Florida Department of Environmental Protection

The mining of pebble phosphate began in 1888 in central Florida and in the 1960s in Hamilton County. Today phosphate mining occurs primarily in the central Florida area (Polk, Hillsborough, Manatee and Hardee counties). The central Florida phosphate mining region covers approximately 1.3 million acres of land known as the "Bone Valley."

Processing - The Phosphate Risk

In Florida, after the phosphate rock is extracted, the ore is dumped into a pit at the mine site, and high-pressure water guns turn it into slurry. The slurry is pumped to a beneficiation plant. At the processing plant, the slurry mixture goes through a two-step process to separate the phosphate …

Phosphate Flotation - Mineral Processing & Metallurgy

For Phosphate, flotation is, in general, very important to upgrading the phosphate rock and is employed in this study to beneficiate a 20% P2O5 feed content to a 30-32% P2O5 content. The growing fertilizer industry has increased the demand for phosphate rock from which super-phosphates are produced. The fertilizer market is very competitive.

Upgrading Phosphate Ores with Rotary Kilns

Phosphate Rock | Minerals Education Coalition

The term phosphate rock (or phosphorite) is used to denote any rock with high phosphorus content. The largest and least expensive source of phosphorus is obtained by mining and concentrating phosphate rock from the numerous phosphate deposits of the world. Some phosphate rock is used to make calcium phosphate nutritional supplements for animals.
