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.

Uranium from Phosphates

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. Higher uranium prices and process refinements have changed the economic situation.
