More than 80% of the world’s production of zinc from its concentrate is obtained by the roastleach-electrowin hydrometallurgical process. In the roast-leach process, very pure zinc sulphate solution must be prepared for zinc electrowinning, therefore, the purification process is one of the most important unit processes in zinc hydrometallurgy. The conventional methods for the zinc solution puri...
Background and aims: Spray tower is a cost effective and simple equipment for ammonia gas purification. But its’ appropriate performance in the removal of ammonia gas is under question. In this study, the effect of nozzle number, concentration of input ammonia gas and scrubbing liquid pressure over the removal efficiency of spray tower was studied. Methods: In present study, a spra...
