Phosphorus is mined primarily as phosphate rock, a fairly common rock found worldwide. It takes about 1 ton of phosphate to produce 130 tons of grain, although this figure is highly variable depending on soil conditions, farm history, crop type, and fertilizing efficiency (Vaccari, 2009).
Phosphate Rock – Scenes at the Great South Carolina Mines, New York Times, October 18, 1881). Otto A.

Jul 21, 2020· Phosphate rock mining originally started in South Carolina 1867 for manufacturing of phosphate fertilizers (Van Kauwenbergh 2010). In the early 20th century, new complex fertilizers were created that contained phosphoric acid, as well as ammonium nitrate and potassium chloride, commonly called NPK fertilizers (UNEP/UNIDO 2000).
Phosphate Rock Statistics and Information. Phosphorus is an essential element for plant and animal nutrition. Most phosphorus is consumed as a principal component of nitrogen-phosphorus-potassium fertilizers used on food crops throughout the world. Phosphate rock minerals are the only significant global resources of phosphorus.
phosphate products, chiefly fertilizer, supplying 25% of the world demand (Jasinski, 2010). The US does not export phosphate rock, but did import 2.5 million metric tons to meet its domestic and foreign demands for fertilizer (Jasinski, 2011). Three other states currently mine phosphate rock—North Carolina, Idaho, and Utah (Jasinski, 2012).
Phosphate Rock 101. Phosphate rock is the only significant commercial source of the element phosphorus. It consists of the calcium phosphate mineral apatite together with quartz, calcite, dolomite, clay, and iron oxide as the so-called gangue constituents. Phosphate rock (or phosphorite) refers to phosphate ores that have been commercially mined.
Phosphate rock mined in North Carolina does not contain pebble rock. In processing this type of phosphate, 2-mm (0.078 in.) or 10-mesh screens are used. Like Florida rock, the fraction that is less than 10 mesh is treated by two-stage flotation, and the fraction larger than 10 mesh is …
In 2020, phosphate rock ore was mined by five firms at 10 mines in four States and processed into an estimated 24 million tons of marketable product, valued at $1.7 billion, free on board (f.o.b.) mine. Florida and North Carolina accounted for more than 75% of total domestic output; the remainder was produced in ...
Phosphate rock mined in North Carolina does not contain pebble rock. In processing this type of phosphate, 10-mesh screens are used. Like Florida rock, the fraction that is less than 10 mesh is treated by 2-stage flotation, and the fraction larger than 10 mesh is used for secondary road building.
Phosphate mining brought between $300,000 to $400,000 annually into South Carolina by the early 1880s, and State of South Carolina was receiving revenues of $1 per ton for all phosphate rock mined out of the river beds (Snowden 1920). By 1890, these state revenues came to over $250,000 per year (Moore 1978:371).
Bench Scale Flotation of Sedimentary Phosphate Rock with Hydroxamic Acid Collectors J.D. Miller*, X. Wang*, and M. Li* ABSTRACT It has been discovered that water insoluble alco holic solutions of alkyl hydroxamic acids serve as selective collectors for the flotation of …
May 13, 2018· Phosphate is a rock composed of Calcium phosphate – the mineral apatite. Calcium fluorapatite is the specific type that makes up vertebrate bones and teeth. Phosphorus is present in all organisms and a critical component of many life sustaining molecules.

Jun 15, 2015· South Carolina's phosphate industry was the world leader until the 1890s, when bad politics, bad luck, and bad weather brought on a rapid decline. Although the river industry contributed over $2,805,000 to the treasury between 1870 and 1892, Governor Benjamin Tillman—no friend of the Charleston elite—sought greater income from, and ...
