Abstract
A method for the production of Group IA salts during a process for the recycling of industrial waste streams containing Group IA compounds and iron and/or zinc compounds, by heating the waste stream in a reducing atmosphere, treating the exhaust fumes from the heating step with an ammonium chloride leaching solution resulting in a Group IA salt containing precipitate, and recovering the Group IA salts from the precipitate.
