Title: Carole Allen: Innovator in Zinc Processing
Introduction
Carole Allen is a distinguished inventor based in Pierrefonds, Canada. She has made significant contributions to the field of zinc processing, holding three patents that showcase her innovative approaches to extracting zinc oxide from complex sulfide materials.
Latest Patents
Her latest patents include a process for the reduction of zinc oxide from complex sulfide concentrates using chloride processing. This invention provides an apparatus and a process for producing zinc oxide from zinc-bearing materials. The process involves leaching complex sulfide material with hydrochloric acid, ferric chloride, and oxygen. It also includes precipitating iron from the leach solution using lime and oxygen, followed by the removal of copper, silver, cadmium, cobalt, and lead through cementation with zinc dust. The final steps involve precipitating zinc oxide from the leach solution using lime and regenerating hydrochloric acid from a calcium chloride leach filtrate solution.
Another notable patent is focused on the production of zinc oxide from complex sulfide concentrates using chloride processing. This process similarly involves leaching the complex sulfide material with hydrochloric acid and oxygen, precipitating iron using magnesium oxide, and removing various metals through cementation with zinc dust. The remaining magnesium chloride leach solution is then spray roasted to regenerate hydrochloric acid and magnesium oxide.
