Latest Patents
One of Sjoberg's latest inventions is an electrowinning system. This invention relates to an electrowinning cell designed for extracting metals in powder form from solutions while simultaneously oxidizing the solution. The cell features radially extending electrodes that comprise mutually alternating anodes and cathodes. It also includes a diaphragm that separates the anode and cathode chambers, with the cathode chamber forming an outer space. Additionally, a stirring mechanism is arranged in the anode chamber to ensure a large flow of electrolyte across the anode surfaces. The base of the cathode chamber is preferably conical in shape.
Another significant patent is a method for selectively recovering lead from complex sulphidic non-ferrous metal concentrates. This method utilizes an electrolytic cell that incorporates at least one anode and one cathode, along with an electrolyte containing chlorine ions. The process occurs at a temperature below the boiling point of the concentrate-containing electrolyte and at a pH below 7. In this method, sulfur present in the concentrate is converted into its elementary form, allowing the majority of the lead content to pass into solution and be selectively precipitated through cathodic processes. The invention is characterized by slurrying the concentrate in an electrolyte with a chloride-ion strength above about 2 M, preferably in the range of 3-5 M, to form a suspension that flows into contact with the anodes in the cell.
