Title: Simo A Makipirtti: Innovator in Metallurgical Processes
Introduction
Simo A Makipirtti is a notable inventor based in Nakkila, Finland. He has made significant contributions to the field of metallurgy, particularly in the processes related to the removal of impurities from molten metals. With a total of 11 patents to his name, Makipirtti's work has had a substantial impact on the industry.
Latest Patents
Among his latest patents, one includes an apparatus for the removal of impurity components from sulphidic materials. This innovative process involves preliminary smelting of crude metal to produce molten sulphide and molten arsenide-antimonide phases. The method allows for the treatment of these phases with elemental sulphur vapor, leading to the continuous sulphuration of the conjugate melt system under reduced pressure. This process effectively volatilizes harmful elements such as arsenic, antimony, bismuth, lead, and tin. Another significant patent focuses on the separation of gold and silver from complex sulfide ores. This process involves heating the sulfide ore at high temperatures and specific sulfur pressures to prepare the metal compounds for subsequent cyanide leaching, ultimately separating the valuable metals from the residue.
