An experimental investigation of leachate generation predictions of waste from copper sulphide ore processing
… formation from mine wastes due to oxidation of sulphide minerals. AMD enhances the mobilisation of trace and minor metals contained in wastes, therby generating contaminated leachate, which may pollute the ground and surface water. It is imperative to minimise post-closure environmental impacts …

An investigation into the feasibility of bioleaching copper sulphide ore of Nchanga mine, Chingola, Zambia
… is now well established for extraction of copper from its low-grade, mixed oxide/sulphide ores in bioheap operations (Watling, 2006). It is claimed bioleaching may be a cheaper alternative to other traditional metal extraction techniques such as smelting and therefore more suitable to treat …

An investigation into the effect of potential modifiers on the flotation of a copper sulphide ore
… electrochemical in nature in the flotation of sulphide minerals which have semiconducting properties. Electrochemical mechanisms have two valuable implications in flotation, the potential across the mineral/solution interface determines flotation recovery and the anodic oxidation reaction …

The role of collectors in the flotation of partially oxidised copper ores
… performance of partially oxidised and oxidised copper sulphide ores were investigated in this study. More specifically, the role of the functional groups of the collectors, their dosages and the effect of collector mixtures and their dosages were investigated. Batch flotation tests were used to …

Compositional and textural analysis of host-rock diamictite matrix at the Kakula copper deposit, Democratic Republic of Congo
… resource, 1% cut-off) in the central African copperbelt, Democratic Republic of Congo. Copper-sulphide ore (chalcocite, bornite, chalcopyrite) at Kakula is predominantly disseminated in the fine-grained matrix of clast-poor (≤20% clasts ≥2 mm) subaqueous debrite (diamictite), at the base of …

Generalised strategy for predicting environmental characteristics of solid mineral wastes : a focus on copper
… of such. There is also a requirement for a more systematic and rigorous approach, which will ensure that the necessary data and information is integrated into the early decision stages of an environmental performance assessment programme and, ultimately, project life cycle in a time and cost …

Investigation of the Geology, Structural Setting and Mineralisation the Copper-Sulphide Deposits in the Messina Area, Limpopo Mobile Belt, South Africa
… structural setting and mineralisation of copper-sulphide deposits in the Musina area, located in the Central Zone of the Limpopo Mobile Belt of South Africa. The Messina copper deposits are located in the eastern part of Limpopo Province near the border with Zimbambwe. The deposits stretch …
