Title: Esko O Nermes: Innovator in Lead Separation Technology
Introduction
Esko O Nermes is a notable inventor based in Turku, Finland. He has made significant contributions to the field of metallurgy, particularly in the separation of lead from sulfidic concentrates. With a total of 3 patents to his name, Nermes has developed innovative procedures that enhance the efficiency of lead production.
Latest Patents
Nermes' latest patents include an "Apparatus for the separation of lead from a sulfidic concentrate." This invention involves feeding a finely-divided concentrate, a silicate-high slagging agent, and air or oxygen-enriched air into the upper section of a suspension reaction shaft of a flash-smelting furnace. The process forms a suspension and oxidizes the lead to lead oxide. The gases are removed via a riser pipe, and the melt is discharged from the lower furnace for further treatment. The slagging agent is fed at a rate that ensures all melt is of the slag type, directing it to a reduction stage to separate raw lead.
Another significant patent is the "Procedure for producing lead bullion from sulphide concentrate." This procedure utilizes suspension smelting to produce lead bullion from sulfidic concentrates with low proportions of iron and slag-forming substances. It employs oxygen or oxygen-enriched air, maintaining equilibrium between the slag containing lead oxide and the refinable lead bullion. The lead oxide content can be lowered without increasing the sulfur content of the bullion by regulating temperature and other factors.
