Thesis (MTech. degree in Chemical Engineering)--Tshwane University of Technology, 2008. / Studies the leaching characteristics of the flotation tailings at different temperatures and pressure in chloride media using an autoclave.Subsequently, to assess and compare the leachability under atmospheric and oxidation pressure leaching conditions. The parameters employed to study atmospheric and oxidative pressure leaching were as follows: Sodium chloride concentration, oxygen partial pressure, % feed solids and particle size distribution.HNO3 acid concentration was kept constant in most of the leach tests. The development of a mathematical reaction rate model that describes the leaching kinetics. The rate values are subsequently used to model the leaching reaction.
