"BENEFICIATION OF HIGH-MgO SEDIMENTARY …

Dolomite [CaMg(CO3)2] is an intolerable impurity in phosphate ores due to its MgO content. Traditionally, the Florida phosphate industry has avoided mining high-MgO phosphate reserves due to the lack of an economically viable process for removal of dolomite. However, as the high grade phosphate reserves become depleted, more emphasis is being put on the development …

In the beneficiation of phosphate ore by the flotation of the siliceous material, the utilization of a condensate of a polyethylene polyamine, having from 10 to 24 carbon atoms, with a fatty acid, fatty acid ester or a fatty acid and an alkylolamine improves the separation of phosphate from silica. This improvement is especially great in the presence of unreacted fatty acid.
