Abstract
A method for the production of zinc ammonium chloride complex salts for use as galvanizing fluxes by heating waste materials captured from industrial processes containing zinc in a reducing atmosphere, leaching the resultant captured waste materials in an ammonium chloride solution resulting in a first product solution and a first undissolved materials, adding zinc metal to the first product solution resulting in a second product solution and a second undissolved materials, and adding additional ammonium chloride and/or hydrochloric acid to the second product solution resulting in the production of zinc ammonium chloride complex salts for use as galvanizing fluxes.
