The history of zinc and its use in pre-modern India Ishrat
The extraction of zinc from ores began late in history, mainly because of the fact that it tended to evaporate when smelting in the open was attempted. It was only when closed stills began to be used for liquor distillation that the same method could be adopted for zinc. This technique began to be used in China and India in medieval times, The tonnage of this complex is 7.3MT. Here the Lead grade is 2.04%, Zinc grade is 3.77% and in Sinesar Khurd Complex tonnage is 6.4MT, and the Lead grade is 2.76%, Zinc grade is 5.32% and Silver is 143.5g/t.

PIXE Analysis of Indian Natural Lead–Zinc Ores and Rocks
A number of Indian natural Pb–Zn ores and rocks have been studied by using complementary and non-destructive proton-induced X-ray emission (PIXE) technique. Sixteen elements including Co, Ni, Cu, Zn, Ga, As, Fe, Mn, and Pb were established in these ores and rocks, which may be useful to interpret the various geochemical ABSTRACT In recent years, lead and zinc, emerge to become one of the most widely used non-ferrous metals for their growing demand in lead-acid batteries, galvanization, radio-active shielding, alloy, and pigments, etc. With continuous exploitation and expanding plant capacity, exhaustion of primary high-grade lead-zinc resources has Beneficiation of Lead-Zinc Ores A Review Semantic Scholar
