eagent chemistry plays a vital role in numerous unit processes of
mineral processing for separation of valuable minerals from gangue.
For selective separation, proper choice of reagent is obligatory. Flotation is
the most adoptable unit process for copper beneficiation. The process of
flotation is extremely challenging due to interdependence of various operating
parameters. Current study focused on the selection of reagent system based
on the complex mineralogy of Malanjkhand copper-molybdenite deposit. The
Malanjkhand porphyry copper deposit is of mixed type (both copper sulphide
and copper oxide minerals) and lean grade ore. After continuous mining, the
deposits are now left with low grade ores which contain copper sulphide as
the major valuable mineral along with higher quantity of silica. In this case,
flotation becomes tougher due to mixed mineralic system. From past reviews,
the recovery of copper from sulphide mineral using xanthate and pine oil is
relatively easy, but mixed oxide-sulphide minerals do not respond to traditional
sulphide collector. There is no common reagent to recover copper from both
oxide and sulphide mineral, which is a great challenge in flotation of both
the minerals simultaneously. Therefore, a comparative flotation study was
carried out using traditional sulphide collector (sodium iso propyl xanthate-
SIPX), hydroxamate (benzo hydroxamic) collector and mixed (SIPX + benzo
hydroxamic) collector system to understand how the reagent chemistry
influence the selectivity in the flotation of mixed copper ore.
