Abstract

Procedure for precipitating zinc oxyhydroxide suitable for electrolysis from zinc chloride solutions, in particular, those obtained by elution in the process of ionic exchange of lyes from wet treatment of different minerals and pyritic products, such as the ashes of roasting of sulphated or chlorinated pyritic minerals, and of the solutions obtained in the retention of volatile chlorides in the treatments of chloridation volatilization, characterized in that the acid solution of zinc chloride is added, at a temperature of 50- 60º, an alkali to neutralize the free acidity, then adding ammonia, gaseous or in aqueous solution, to precipitate the zinc in the form of zinc hydroxide, after which the suspension is heated to 95-100ºC to optimize the precipitation yields, separating, finally, the precipitate of zinc oxyhydroxide, suitable for the production of zinc electrolyte ico (Machine-translation by Google Translate, not legally binding)
