Sep 24, 2013018332At Smoky Canyon, the trucks cart phosphate ore to an onsite mill where it is ground into a fine powder and mixed with water in a large vat into a slurry that resembles chocolate milk. The slurry then travels 84 miles through an underground pipeline a Simplot processing plant in Pocatello.
Ore grade in the phosphate mining industry is one of the primary criterion used to differentiate phosphate ores. Grade is oft\n expressed in terms of bone phosphate of lime \ or phosphorus pentoxide \. The use of BPL is from the outdated belief that P in PR existed as tricalcium phosphate.
Southeast Idaho Phosphate Mining. The process of mining phosphate ore from the earth generated open pits and piles of overburden materials covering the phosphate ore. The overburden material is naturally elevated in selenium and other trace metals. When exposed to the elements, these overburden piles can release selenium and other trace metals to the environment.
Regardless of how phosphate ore is extracted, it contains impurities that must be removed before it can be used for the manufa\ture of fertilizer. Among the common impurities are clay minerals, sand \ , carbonates, iron oxides, and others.

The ore reserves have been estimated as 100 million tons of phosphate (200 million tons as proved ore). The mine has started to export the ore since 1995. The exploration and experimental studies were started in 1975 and recommended the following Extraction of the phosphate layer from two zones, underground mine, where the thickness of
Jordan Phosphate Mines Co. is a public shareholding limited company, founded in 1949. Its current capital is JOD 82.5 million. The Company aims at mining and processing phosphate ore in Jordan.. During the last six decades, the Company has assumed its pioneering position among the international companies in the fields of mining and producing fertilizers.
The Douglas Mine and Concentrator located nine miles south of Drummond, Montana on Douglas Creek were a major part of this development. Montana Phosphate Products Company began underground mining at this location in 1962. By 1964 the mine employed approximately 110 workers and was steadily producing phosphate rock.
