Title: Rolf E Malmstrom: Innovator in Lead Separation Technology

Introduction

Rolf E Malmstrom is a notable inventor based in Helsinki, Finland. He has made significant contributions to the field of metallurgy, particularly in the separation of lead from sulfidic concentrates. With a total of 2 patents, his work has advanced the efficiency and effectiveness of lead extraction processes.

Latest Patents

Malmstrom's latest patents include an "Apparatus for the separation of lead from a sulfidic concentrate" and a "Process for the separation of lead from a sulfidic concentrate." Both patents describe a method where finely-divided concentrate, a silicate-high slagging agent, and air or oxygen-enriched air are fed into the upper section of a suspension reaction shaft of a flash-smelting furnace. This 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 introduced at a rate that ensures all melt is of the slag type, directing it to a reduction stage to separate raw lead.
