principles and practice of sulphide mineral flotation

Synopsis. This paper presents both the fundamentals of sulphide mineral flotation and the practical aspects of sulphide ore flotation. The fundamental aspects of the flotation of sulphide minerals both in the absence and presence of thiol collectors are discussed in relation to their crystal structure, surface chemistry and electrochemical characteristics

redox potential control during flotation of a sulphide

Aug 15, 2017 · The critical role of dissolved oxygen on the flotation of sulphides has been widely reported (e.g. Buckley and Woods, 1997).The oxygen may also undergo reduction according to reaction . (4) O 2 + 2 H 2 O + 4 e-↔ 4 OH- Given the role of pH already alluded to it is clear that redox potential, which is a function of pH and DO, is a key indicator of the condition of a pulp with respect to its

ore sorting: efficiently optimise the treatment of ores in

In southern Africa, two x-ray sorters are used to pre-concentrate sulphide gold ore into two different grain size categories. While the input material has an average gold content of less than 0.8 g/t, the sorted product achieves a concentration of more than 4 g/t with an efficiency of approximately 90%

In South Africa, chromite is one of the main gangue constituents of especially UG2 ore, making up to between 20 and 60% by mass of the ore (cf. Figure 3). Although the main minerals targeted in flotation are generally the base metal sulphides, viz. pyrrhotite, pentlandite, and chalcopyrite, a certain amount of chromite reports to the flotation
