Title: Werner Sauerland: Innovator in Pyrite Treatment Technologies
Introduction
Werner Sauerland is a notable inventor based in Voerde, Germany. He has made significant contributions to the field of mineral processing, particularly in the treatment of pyrite-containing minerals. With a total of 2 patents, his work focuses on improving the efficiency and environmental impact of coal processing.
Latest Patents
Sauerland's latest patents include a "Method of and apparatus for the treatment of pyrite-containing mineral" and a "Method of and apparatus for the dry separation of pyrite from coal." The first patent describes a process where mined mineral coal containing pyrite is milled and classified into fine and coarse components. The coarse component is recycled and subjected to density suspension, allowing for the separation of a light product predominantly made of coal from a heavy product that includes pyrite and mineral detritus. This heavy product can be combusted in a fluidized bed, producing gypsum and ash as solid residues, which can be safely used in cement or plastic mixtures.
The second patent outlines a dry method for removing pyrite from mineral coal. In this process, coal is mill-dried in a gas stream, and the resulting product is classified to recover a combustible fine fraction and a coarse fraction containing pyrite and detritus. The coarse fraction undergoes density separation, allowing for the return of the light coal fraction to the milling stage while the heavy fraction is further processed to recover pyrite for other uses.
