Title: The Innovative Contributions of Torsten E Jensfelt
Introduction
Torsten E Jensfelt is a notable inventor based in Stocksund, Sweden. He has made significant contributions to the field of metallurgy, particularly in the recovery of lead and other metals from complex raw materials. With a total of 2 patents to his name, Jensfelt's work showcases his expertise and innovative approach to solving industry challenges.
Latest Patents
Jensfelt's latest patents include a method for the manufacture of lead from sulphidic lead raw material. This process involves recovering lead from sulphidic lead raw material containing impurities such as bismuth, arsenic, antimony, and tin. The method utilizes flame-smelting with an oxygen-containing gas, where the oxygen potential and temperature are carefully controlled. This results in a lead-sulphide melt that is substantially free of volatile, sulphidic, and metallic impurities. The lead-sulphide melt is then brought into contact with an oxidic lead material, allowing for the recovery of lead through separation after a reducing process if necessary.
Another significant patent by Jensfelt is a method for recovering the metal content of complex sulphidic metal raw materials. This process employs an autogenous flame-smelting technique, preferably conducted in a vortex with an oxygen-containing gas. The raw materials are smelted in a furnace with an excess of oxygen and an acid slag former, such as silica, to create a melt rich in metal-oxide silicate and low in sulphur. The metal phase formed in the furnace is separated from the silicate phase, allowing for the recovery of non-iron metals through selective reduction.
