His innovative methods have the potential to enhance the efficiency of zinc production while minimizing environmental impact.
Latest Patents
Arne Bjune holds a patent for a method of producing zinc from chloride solutions. This method focuses on the selective extraction of zinc from solutions that also contain iron and copper. The process utilizes tri-n-butylphosphate in an organic solvent to extract zinc in the organic phase. The extraction is optimized for chloride solutions with reduced lead content and a maximum copper concentration of 50 grams per liter. The zinc-containing organic phase is subsequently washed, and zinc is back-extracted for electrolysis in a diaphragm cell. The electrolyte used is returned to the back-extraction step, allowing for a sustainable cycle. The raffinate from the zinc extraction is then employed for repeated leaching of metals after reoxidation.
