Comparative analysis of dolomite/francolite flotation techniques
The results of bench-scale testing of five flotation processes for the separation of dolomite from phosphate are discussed. Each process is compared in terms of phosphate recovery, MgO content of the concentrate and reagent consumption. Water quality was found to play a major role in the performance of these processes. The effect of water hardness, in addition to other …

Beneficiation of Phosphate Ore
Beneficiation of Phosphate Ore examines various methods for processing phosphate rock, an important mineral commodity used in the production of phosphoric acid. The majority of phosphoric acid is produced by the wet process, in which phosphate rock is reacted with sulfuric acid to produce phosphoric acid and gypsum (calcium sulfate dihydrate).

Beneficiation of a dolomitic phosphate pebble from Florida
A different version of the modified Crago-TVA process was developed for beneficiation of a weathered dolomitic phosphate pebble from Florida. In this process, the phosphate mineral first is concentrated with fatty acid and fuel oil in the overflow and then refloated to remove additional coarse dolomite in the underflow.
