Latest Patents
One of Arentzen's latest patents is titled "Impurity segregation in copper by controlled cooling treatment." This innovative process involves subjecting molten partially refined copper to controlled cooling, allowing impurities to coalesce into larger agglomerations. As a result, these impurities become segregated at the boundaries of the copper crystals, making them less susceptible to dissolution in the electrolyte. This method enables the use of less refined copper starting material while achieving a comparable final cathode copper product.
Another significant patent is "Oxidizing flux for simultaneous smelting/converting sulfides of high-gangue content." This method focuses on producing a metal matte from unroasted high-gangue content ore containing iron sulfides. By using ferric oxide as a flux, the process reacts with the iron sulfides to provide the necessary oxygen for removal from the matte. This innovation reduces or eliminates the need for a separate converter step, streamlining the production process.
