Zinc being more reactive than hydrogen, displaces it from sulphuric acid. When zinc reacts with dilute sulphuric acid hydrogen gas is evolved, with an effervescence. ... When dilute sulphric acid reacts with zinc granules, thenzinc sulphate and hydrogen gasare formed. (i) ZnS + H2SO4 →...
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 present investigation deals with the dissolution kinetics of zinc from its sulphide concentrate in the presence of sodium persulphate (SPS) as an oxidant in sulphuric acid media. Leaching variables such as leaching time, temperature, acid and oxidant concentration, Eh, and the particle size of...
In the present paper, the hydrometallurgical processes have been described for the recovery of zinc from the secondaries using sulphuric acid, hydrochloric acid, ammoniacal solution and sodium hydroxide etc. as lixiviants. The leach solution thus obtained has been purified with respect to dissolved ...
Hydrogen is a product of the reaction betweenzincand sulphuric acid. 氢是锌和硫酸反应的生成物. 辞典例句 The fusion of copper andzincmakes the metal brass. 铜和锌的熔化制成黄铜. 辞典例句 Combinations ofzincsalts and creosote have also been widely employed. ...
Reaction with Sulphuric Acid Zinc sulphide reacts with sulphuric acid to give zinc sulphate and hydrogen sulphide. The chemical equation for the reaction can be given as, \({\rm{ZnS}} + {{\rm{H}}_2}{\rm{S}}{{\rm{O}}_4} \to {\rm{ZnS}}{{\rm{O}}_4} + {{\rm{H}}_2}...
