mining and mineral processing of phosphates

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.

Phosphate Beneficiation Process

Large scale mining and processing of phosphate is essential for operating at a profit. In the Florida area, Phosphate Beneficiation by flotation unlocked the door to vast tonnages of ore which in the past could not be recovered by conventional washing methods which saved only the coarser pebble phosphate. Many of the areas now being mined contain very little or no pebble phosphate, so the …

Processing - The Phosphate Risk

At the processing plant, the slurry mixture goes through a two-step process to separate the phosphate rock from sand and clay particles. The first stage is a concentrating process that separates the phosphate pebbles from everything else. The average operation can wash and size a maximum of 375 tons of pebbles in an hour.

Phosphate minerals - Wikipedia

Phosphate rock has high concentration of phosphate minerals, most commonly of the apatite group. It is the major resource mined to produce phosphate fertilizers for the agriculture sector. Phosphate is also used in animal feed supplements, food preservatives, anti-corrosion agents, cosmetics, fungicides, ceramics, water treatment and metallurgy.

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.”
