Latest Patents
Johansson's latest patents include innovative methods for recovering precious metals and valuable metal content from contaminated copper. The first patent describes a method for pyrometallurgically recovering precious metals such as gold, silver, and platinum from halogen-bearing materials rich in silver. This method involves dispersing the material in a molten charge that can dissolve precious metals while reacting with halogens to form metal halogenides, which are then separated and processed to recover the precious metals.
The second patent focuses on recovering valuable metal content from a mix of contaminated copper raw materials. This method adjusts the halogen content of the mix to ensure it is stoichiometric concerning impurities. The mix is then heated in a furnace to expel impurities and smelt the ingredients, ultimately recovering the valuable metal content through conventional methods.
