“…Quantitative X-ray diffraction (QXRD) was used to cross check the mineral identity and their relative abundance at the University of Cape Town, since there was already a working knowledge of the mineralogy of the ore (Ryan et al, 1982;McClung and Viljoen, 2011) . The Rietveld method was used to quantify the abundance of mineral phases present in the samples.…”

“…Much of the work that has been done gives emphasis to the type and amount of minerals present and relating it to processing behaviour (Alves and Hagni, 2008;Becker et al, 2008;Liang and Wang, 2008;Lotter, 2010;Rule and Schouwstra, 2011;Uliana et al, 2011). Some have looked at the texture of the ore Chetty et al, 2012;Donskoi et al, 2008;McClung and Viljoen, 2011;Meadows et al, 2012;Rozendaal and Horn, 2012;Thompson et al, 2011;Zhou and Gu, 2008). In these examples texture is classified qualitatively based on abundance of mineral, metal/mineral deportment, shape of mineral, mode of occurrence of the mineral of interest (i.e.…”

The aim of this study is to apply process mineralogy as a practical tool for further understanding and predicting the flotation kinetics of the copper sulfide minerals. The minerals' composition and association, grain distribution, and liberation within the ore samples were analyzed in the feed, concentrate, and the tailings of the flotation processes with two pulp densities of 25wt% and 30wt%. The major copper-bearing minerals identified by microscopic analysis of the concentrate samples included chalcopyrite (56.2wt%), chalcocite (29.1wt%), covellite (6.4wt%), and bornite (4.7wt%). Pyrite was the main sulfide gangue mineral (3.6wt%) in the concentrates. A 95% degree of liberation with d 80 > 80 µm was obtained for chalcopyrite as the main copper mineral in the ore sample. The recovery rate and the grade in the concentrates were enhanced with increasing chalcopyrite particle size. Chalcopyrite particles with a d 80 of approximately 100 µm were recovered at the early stages of the flotation process. The kinetic studies showed that the kinetic second-order rectangular distribution model perfectly fit the flotation test data. Characterization of the kinetic parameters indicated that the optimum granulation distribution range for achieving a maximum flotation rate for chalcopyrite particles was between the sizes 50 and 55 µm.
