ABSTRACT:
A method for the recovery of zinc products, including zinc oxide and elemental zinc, and optionally iron-carbon feedstocks, from industrial waste streams containing zinc and iron, by treating the waste streams with carbon and an ammonium chloride solution, separating any undissolved components from the solution, displacing undesired metal ions from the solution using zinc metal, treating the solution to remove therefrom zinc compounds, and further treating the zinc compounds and the undissolved components, as necessary, resulting in the zinc products and the optional iron-carbon feedbacks.
