Abstract: The present application refers to zinc recovery process from steelworks powder, and to obtain a zinc sulfate solution with 12% Zn by weight with the expected degree for fertilizer. Such an approach can aim to add value to a steelmaking waste, by partially converting environmental liability in commercial product taking advantage of the steelworks' powder as a raw material for the production of a liquid fertilizer and ready for use, containing zinc and sulfur with low liquid effluent production. Such an approach can be advantageous as to simplicity, use of mild temperatures, use of a single reactant, overall conversion of the reactants into a product solution of commercial quality, ready for use as a foliar fertilizer with low generation of wastewater and without generation of additional waste.
