Mineral Resource of the Month: Phosphate Rock | EARTH …

Mining first began in the United States in 1867 in South Carolina. Phosphate rock was discovered in central Florida in the 1880s, and because of the extensive, high-quality deposits and lower mining cost, it quickly became the leading phosphate-producing state. Currently, phosphate rock is mined in Florida, Idaho, North Carolina and Utah.

The Mining Process - The Phosphate Risk

When the permitting process is complete, mine construction begins, including road building to the site. In Florida, the phosphate rock is extracted by a process referred to as strip-mining. Unlike mining in other states, phosphate deposits are found closer to the surface, about 30-40 feet below ground.

Chemical Processing of Phosphate

Chemical Processing of Phosphate. The phosphate mineral as it exists in the ground is not soluble and is hard for the plant to access. To provide the plant with the phosphate it needs, in a form it can take up through its roots, the phosphate rock is converted to phosphoric acid.

Mineral processing - Wikipedia

A number of auxiliary materials handling operations are also considered a branch of mineral processing such as storage (as in bin design), conveying, sampling, weighing, slurry transport, and pneumatic transport. The efficiency and efficacy of many processing techniques are influenced by upstream activities such as mining method and blending.

How phosphate is mined and processed

rock phosphate can become soluble (and available to plants) either by chemical weathering or through the actions of certain types of plants. The solubility also depends on rock type and the pH of the soil; phosphorus is most soluble when contained in sedimentary rocks as opposed to igneous rock, and when soil pH is between 5.5 and 7.2.
