Eight plants for the recovery of uranium from phosphoric acid have been built and operated in the United States since 1976. Plants have also been built in Belgium, Canada and Taiwan, China. 5.

Wet process sulfuric acid acidulation is the most commonly used tech-nique for improving the agronomic suitability of phosphate rock. The majority of finished P-containing materials used in North American agriculture are made from wet process phos-phoric acid. Phosphoric acid is made from the reaction of sulfuric acid with phosphate rock.

Energy Agency (IAEA) estimates that Morocco's uranium resources in phosphate deposits at around 6 million tons, which corresponds to twice the world's resources in uranium deposits. Figure 1. Phosphate ore processing. The average uranium content in phosphate rock is low at 50-200 parts per million (ppm) or 0.005-0.020 percent.

for 86% of domestic production of phosphate rock. The remainder was produced in Idaho and Utah. More than 90% of the phosphate rock consumed in the United States was used to manufacture wet process phosphoric acid for fertilizer, animal feed, and chemical uses. One company in Idaho produced elemental phosphorus from its own ore.

calcining step is omitted, and the beneficiated rock is transferred directly to the phosphoric acid production processes. Phosphate rock that is to be used for the production of granular triple super phosphate (GTSP) is beneficiated, dried, and ground before being transferred to the GTSP production processes.

Uranium from Phosphates (Updated August 2015) Rock phosphate deposits contain many million tonnes of uranium, which may be extracted as a by-product of making fertilisers. Some 20,000 tonnes of uranium has already been obtained from these rock phosphate deposits, but the process became uneconomic in the 1990s.

4, the dihydrogen phosphate ion, which in turn is the conjugate base of H 3 PO 4, phosphoric acid. A phosphate salt forms when a positively charged ion attaches to the negatively charged oxygen atoms of the ion, forming an ionic compound.
