Beneficiation is usually necessary to upgrade the ore to the acceptable grade for the phosphate industry, ie, a P 2 O 5 concentration > 30%, a CaO/P 2 O 5 ratio < 16, and a MgO content < 1% 27Phosphates, compounds of the element phosphorous, are produced from relatively abundant supplies of phosphate rock Keywords Phosphoric Acid; Phosphate Rock; Phosphate Deposit; Froth Flotation; Beneficiation Plant; These keywords were added by machine and not by the authors This process is experimental and the keywords may bePhosphorus and Phosphates | SpringerLink
2014年12月4日· Unfortunately, process control in phosphate beneficiation plants is still primitive, after 100 years This is due to the following difficulties in analyzing the plant slurry: (1) Slurried sedimentary phosphate rock samples from Florida were previously analysed by onstream Xray diffraction (Midfox) in the laboratory at Mintekphosphate rock, and other minerals, are becoming exhausted, These operations not only pro duce a higher grade of product, but allow larger amounts to be recovered, beneficiated, and used, even in the case of such a lowpriced product as phosphate rock The matrix from the Florida phosphate pebble deposits is received at the beneficiationProcess Industry Lecture 1315 Phosphorus Industries
