2016-12-13 The mines of Rajasthan have given definite evidence of zinc production going back to 6th Century BC. Distillation process however was being used only from the 12th century AD, thus India is the first to produce zinc by distillation processes. We are sure that the following story of early zinc production and lead about the ancient Indian ...

2021-2-12 galvanic zinc Zinc is the most frequently deposited metal in sur-face technology. It serves as corrosion protection and provides cathodic protection for the base material. This means that the steel becomes the cathode and the zinc forms a sacriicial anode and dissolves at the imperfec-tions of the layer. Below 100°C it is brittle, in the range of
