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 (PO 4 3–) or runoff losses from PR products like PO 4 3– fertilizers, animal feeds, and detergents could cause eutrophication of surface waters enriched in PO 4 3– by these ...
Tailings are the wastes generated by several physical and chemical beneficiation processes that may be used to separate the valuable metal or mineral from the interbedded rock; the choice of process depends on the composition and properties of the ore and of the gangue, the rock in which the ore occurs.
Lower ore grades, increasing power costs, and environmental regulations are necessitating development of new concepts of mining and matrix transportation. Because one of the ores to be mined in the future contains appreciable amounts of dolomite, research and development efforts are being concentrated on new techniques in beneficiation.
