The copper ore sample was obtained from Northparkes Copper 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.
ore after sulphidisation showed a copper deportment of 0.1 % cuprite, 0.6 % malachite, 0.8 % chalcopyrite and 84.8 % chrysocolla, suggesting that all oxide copper minerals present in the LQ ore, except chrysocolla, are amenable to flotation using SIBX after sulphidisation.
The recovery of copper by sulphidisation and flotation from a mixed ore has been studied in detail in this thesis. Particular focus was given to the effect of pulp chemistry on the sulphidisation mechanism and subsequent flotation response of oxidised sulphide minerals, both of
Thesis (PhDAppliedScience) University of South Australia, 2006 Includes bibliographical references. One of the problems in the flotation of copper sulphide ores in moderately alkaline pH conditions is the misreporting of iron sulphide minerals into copper concentrates, which results in low copper grades.
MSc thesis Synopsis This paper investigates the effects of thiol collectors xanthates, dithiophosphates, dithiocarbamates and mixtures of these on the froth flotation performance obtained with a bornite rich copper sulphide ore from Okiep Copper Mine with a feed grade of 1.8% copper. Batch flotation tests were used to assess the performance in
