Polographic Analysis of Zinc ore concentrates for the determination of Lead, Copper, Cadmium and Zinc

IN the field of inorganic analysis, the polarograph
has been applied successfully for the determination
of many elements under favourable conditions to obtain somewhat greater accuracy than the other instrumental or chemical methods with far less expenditure of time.

The present work was taken up to find out a rapid
and reliable polarographic method for the analysis of
a large number of samples of zinc ore concentrates
required to be analysed during the beneficiation of zinc
ores in this laboratory. The difficulties encountered for
the determination of lead, copper, cadmium and zinc by existing wet chemical methods are well-known. It is often required to separate the metals from each other and the interfering elements also, which makes the process time-consuming.
