The study investigated the acid leaching of phlogopite and the parameters that play a role in the conversion as well as the selectivity of various acids. The parameters investigated were: Temperature, Solid to liquid ratio, Stir speed, Acid concentration, Particle size, Acid purity Quantifying the impact each of these parameters have on the conversion and selectivity allows for better understanding and optimization of the leaching of phlogopite. It was found that the ash diffusion rate limited flat plate shrinking core model was the best model at predicting the leaching with the exception of the overall ion leached by hydrochloric acid which was fitted to an empirical equation. tm2016 mi2026 Chemical Engineering MEng Unrestricted SDG-09: Industry, innovation and infrastructure SDG-12: Responsible consumption and production 2016-07-29T11:02:16Z 2016-07-29T11:02:16Z 2016-04-07 2016 Dissertation Woest, GS 2016, Selective leaching of phlogopite, MEng Dissertation, University of Pretoria, Pretoria, viewed yymmdd <http://hdl.handle.net/2263/56127> A2016 http://hdl.handle.net/2263/56127 en © 2016 University of Pretoria.
