Zinc was recognized in India as a new metal and at Zawar, India, both zinc
metal and zinc oxide were produced from the 12th to the 16th century. The
raw material used for the production of zinc is zinc concentrate, which is
the result of a flotation process after the ore has been mined and milled.
The process begins with the roasting of the concentrate.
The iron and zinc oxides that, after the roasting process, have been
reduced to powder form, are leached with dilute sulphuric acid. The solution
is neutralized and the precipitates i.e. metallic co-products together with
any unwanted contaminants, are removed by filtration.
