Aug 01, 2018nbsp018332The copper ore sample was obtained from Northparkes Copper amp Gold Mine, Australia. This ore was chosen due to its relatively unproblematic flotation characteristics. Such an ore provides a formidable baseline for the identification of the deleterious effects of clays. The chemical assays of the ore sample contains 0.5 Cu, 3.8 Fe, and 0.3 S.
