02-023-050Final

Abstract

The future Florida phosphate deposits are associated with dolomitic limestone impurities. These ores cannot be treated by conventional beneficiation technology to attain an MgO content of less than 1% as required by the fertilizer manufacturers. Thus, the goal of this study was to develop processing methods concentrates of the desired quality. The results are reported in three separate volumes.

Volume 1 includes data about the mineralogy of Florida apatites as gathered by Mineralogical, Chemical, Surface chemical and physical analyses of different samples. In addition, results of other studies such as aging, and flotation kinetics of dolomite and apatite, are presented.
