Based on data found in the IFDC report, the Unites States was thought to hold about 76 per cent of the world's recoverable phosphate product (~30 per cent P 2 O 5) in the late 1970s. As the 2010 IFDC report indicated, world phosphate rock reserves and resources are dynamic due to a wide variety of factors.

From 1869 to the 1940s South Carolina was one of the top five fertilizer-producing states in the nation. 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 …

October 20, 2010 – "The International Plant Nutrition Institute (IPNI) and its predecessor, the Potash & Phosphate Institute (PPI), have long promoted the effective and efficient use of phosphorus (P) fertilizer in crop production. Without balanced and appropriate P input, crop yields are reduced, quality is diminished, and the potential for adverse …
Figure 1. Accumulated Soil P-balances from annual and one-time applications of rock phosphate fertilizer. Treatments are an annual application of rock phosphate (RP) fertilizer at 35 kg P/ha, a single application of RP at 175 kg P/ha, and a treatment receiving only equivalent nitrogen (N) and potassium (K) applications as the …
Phosphate rock (PR) is an important mineral resource with numerous uses and applications in agriculture and the environment. PR is used in the manufacture of detergents, animal feed, and phosphate (PO43–) fertilizers. Leaching or runoff losses from PR products like PO43– fertilizers, animal feeds, and detergents could cause …
And the world commercial phosphate rock production is estimated to be 250 million tons per year, that makes phosphate rock a potential new REEs resource. However, low content of REEs in phosphate rock leads to the technical challenges and cost overages, that hindered the commercial recovery of REEs. In this paper, an …
Phosphate rock and phosphorite are names used for sedimentary rocks that contain at least 15% to 20% phosphate on the basis of weight. The phosphorous content in these rocks is mainly derived from the presence of apatite minerals. Uses of Apatite as Phosphate Rock. Most of the phosphate rock mined throughout the world is used to …
World phosphate rock production decreased at 2.8% between 2016 and 2021. The large decline occurred in mainland China and the United States, while large growth occurred in Africa, the Middle East, and the CIS and Baltic States. Production from countries like Morocco, Saudi Arabia, Jordan, Russia, and Kazakhstan has increased considerably. ...
A vital and indisputable link exists between phosphate rock and world food supply. Phosphate rock is the source of phosphorus used to make phosphatic fertilizers, essential for growing the food needed by humans in the world today and in the future. We modeled the depletion of the known reserves and reserve base (which includes reserves) of …
Fertilizer Outlook and Technology Conference Hosted by The Fertilizer Institute and the Fertilizer Industry Roundtable November 16-18, 2010 Savannah, GA. Numerous articles have suggested phosphorus (phosphate rock) reserves — resources will be depleted in the 21st century. Rosemarin 2004. Rosemarin et al. 2009. Cordell, Dragert and White 2009.
In 2018, the average unit value of imported phosphate rock decreased by 13% to $72.39 per metric ton from $83.45 per metric ton in 2017. the price was calculated using the U.s. census Bureau customs value and included cost, insurance, and freight (table 1). the import price was within range of average world prices.
