Title: Innovations of Gunnar H Boe
Introduction
Gunnar H Boe is a notable inventor based in Kristiansand, Norway. He has made significant contributions to the field of metallurgy, particularly in the extraction of metals from various materials. With a total of 3 patents to his name, Boe's work showcases innovative methods that enhance the efficiency of metal extraction processes.
Latest Patents
One of Boe's latest patents is a hydrometallurgical method for extracting copper from sulphide-containing materials. This method involves leaching the material using a solution containing iron (III) chloride and copper (II) chloride. The leaching process is carefully regulated to maintain the red-ox potential between 430 mV and 460 mV. This regulation allows for the reduction of iron (III) chloride to iron (II) chloride while keeping copper (II) chloride in its bivalent state. Consequently, the copper content is leached as copper (II) chloride, which is then extracted from the leach solution using an organic complex-ion forming extractant.
Another significant patent by Boe focuses on the production of zinc from chloride solutions. This method allows for the selective extraction of zinc from solutions containing iron, copper, and zinc. The extraction is performed using tri-n-butylphosphate in an organic solvent, ensuring that the lead content is minimized. The zinc-containing organic phase is subsequently washed, and the zinc is back-extracted for electrolysis, with the used electrolyte being returned for further processing.
