Title: Innovator Pekka Hanniala: Advancements in Non-Ferrous Metal Production

Introduction

Pekka Hanniala, an esteemed inventor based in Espoo, Finland, holds an impressive portfolio of four patents. His contributions to the field of non-ferrous metal production highlight his commitment to enhancing industrial processes and efficiency.

Latest Patents

Among his notable patents, the first concerns a "Method for reducing non-ferrous metal content in slag in the production of non-ferrous metals occurring in a suspension smelting furnace." This innovative method introduces metallurgical coke into the furnace, with sizes ranging from 1-25 mm, to reduce the non-ferrous metal content in the generated slag. Furthermore, strategically positioned baffles within the furnace help in trapping small particles of copper and nickel, ensuring they settle in the reduction zone rather than being lost with the slag.

Another significant innovation is the "Apparatus for suspension smelting." This invention relates to the suspension smelting process of sulfidic, finely divided raw materials containing metals like copper, nickel, and lead. By utilizing oxygen enrichment, Hanniala's method ensures that the reaction space within the furnace is effectively cooled and that multiple molten phases are created. The degree of oxygen enrichment is critical, set at a minimum of 40%, to raise the temperature of the suspended particles significantly, thus enhancing reaction kinetics.
