The mineral composition of copper–cobalt ores is more complex than that of copper sulfides, and it is also difficult to discard tailing efficiently in primary flotation for the fine-grained disseminated of ore. In this work, a mineral liberation analyzer (MLA) was employed to study the characteristics of minerals. As a significant mineralogical …

Peter has more than fourteen (14) years of processing experience across five (05) processing plants in Central Africa, Zambia …
A Copper Flotation Flowsheet. Because the copper in this type of ore usually assays only plus or minus 1% copper, the porphyry copper operations must be relatively large in order to be commercial. …
The objective of this study was to investigate the floatability of a complex Kansanshi mixed copper ore with a special focus on the sulphidisation process. Controlled potential sulphidisation (CPS) is preferred over slug sulphidisation as the industry standard for the flotation of oxide copper minerals. Two potential ranges were investigated in ...
There are different methods of processing copper mines, such as preferential flotation, bulk-separating flotation, etc. for copper sulfides, and sulphidizing flotation, fatty acid flotation, etc. for copper oxides. ... the ore in the Nchanga processing plant in Zambia contains 4.7% copper. The copper content achieved to 50% ~ 55% …
Selective flotation of copper, depressing cobalt, from the global concentrate obtained in the previous global flotation. Regarding the parameters of this differential flotation, some companies after floating copper and cobalt together, the pH is increased to 9.5 using lime and cyanide is used as a depressant.

pyrometallurgical plants in either Kitwe or Mufurila. The main copper-bearing minerals found at Konkola Mine include bornite (Cu5FeS4), chalcopyrite (CuFeS2), chalcocite (Cu2S) and native copper (Cu).
Zambia Tailings Leach Plant: A World First The first large-scale copper SX plant in the world was commissioned at the Nchanga Tailings Leach Plant (TLP) in Zambia in 1974, with a daily production of 200 t Cu cathode (Holmes et al., 1976). The mixer–settlers, originally configured as four trains of three extract and two strip stages, are long and

The conical stock-pile design included a single reclaim tunnel, providing sufficient capacity for ...
The preferred method for the flotation of oxide and mixed copper ores is sulphidisation. The reagents are typically sodium sulphide (Na2 S) and sodium hydrosulphide (NaHS). Slug sulphidisation, which uses a single slug dose, is generally not preferred because the difficulty in controlling the pulp potential leads to poor mineral …

The intercept is zero, because the adjustment led to the regression line passing through the zero value. It must be borne in mind that, although we study a specific flotation process for copper ores, its oxidized degree can vary within a range. Therefore, the range of copper grades in the feed was also chosen as independent variables for its …
