4 hydrometallurgical zinc smelters, 2 lead smelters, 1 pyro metallurgical zinc-lead smelter, and sulphuric acid and captive power plants in northwest India. Hindustan Zinc’s mining capacity post-expansion will take our mined metal capacity from 1.2 million tonnes to 1.35 million tonnes per annum....

Inhibition of corrosion of zinc in sulphuric acid by ethylaminesSA ZeleRT Vashi
In the electrolytic process the concentrate is roasted, producing sulphur dioxide, which is the basis of the sulphuric acid that is used to leach the roasted concentrate. Most of the by-products and impurities in the resultant leach liquor are removed by successive precipitation stages ('...
Electrowinning processing leaches zinc from the ore concentrate by sulphuric acid (Gupta et al., 1990). The obtained purified solution passes an electrolytic process where the purified solution is electrolyzed between lead alloy anodes and aluminium cathodes. An electrical current is circulated through ...
the oxide is dissolved in sulphuricacid and the zinc obtained byelectrolysis. There are five stable isotopes(mass numbers 64, 66, 67, 68,and 70) and six radioactive isotopesare known. The metal is used in galvanizingand in a number of alloys(brass, bronze, etc.). Chemically it is a...
NCERT solutions for CBSE and other state boards is a key requirement for students. Doubtnut helps with homework, doubts and solutions to all the questions. It has helped students get under AIR 100 in NEET & IIT JEE. Get PDF and video solutions of IIT-JEE Mains & Advanced previous year pap...
The effect of the aqueous pH, and therefore zinc ammine complex formation, on the extraction of zinc was studied. Stripping of the metal from loaded organic phases was carried out at various rates, temperatures (H° = 3·2 kJ mol-1) and sulphuric acid concentrations. The results obtained ...
