To Extract, or not to Extract Uranium from Phosphate

To Extract, or not to Extract Uranium from Phosphate

Oct 31, 2016 Oct 31, 2016 mined. The extraction of uranium from phosphate rock represents a more environmentally and socially responsible form of uranium mining, as phosphate rock is mined anyway for its phosphate component. Thus, it is postulated that extracting uranium from already mined phosphate rock, as schematically described in Figure 1, would lead to cleaner

Mining and Beneficiation – Phosphate Research Network

The mining process of phosphate ore deposits includes prospecting, exploration, mine development and ore exploitation. The ore extraction could be underground or open pit which is the most common method. The main phosphate rock extraction stages in open pit are drilling, blasting, excavating, loading, haulage and dumping

How phosphate is mined and processed

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

Dec 01, 2014 Dec 01, 2014 Phosphate rock mining originally started in South Carolina in 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 - an overview | ScienceDirect Topics

Phosphate Rock - an overview | ScienceDirect Topics

Phosphate rock used for fertilizer is a major NORM due to both uranium and thorium. Phosphate is a common chemical constituent of fertilizer. It is principally mined from apatite and phosphate rocks (phosphorite) in which the concentration of phosphate has been enhanced by sedimentary, igneous, weathering, and biological processes
