Title: Innovations of Peter F Wells in Sulphide Mineral Processing
Introduction
Peter F Wells is an accomplished inventor based in Sudbury, Canada. He has made significant contributions to the field of mineral processing, particularly in the separation of sulphide minerals. With a total of two patents to his name, Wells has developed innovative processes that enhance the efficiency of mineral extraction.
Latest Patents
Wells' latest patents include a "Process for improved separation of sulphide minerals or middlings" and a "Selective flotation process for separation of sulphide minerals." The first patent describes a multi-stage froth flotation process designed to concentrate sulphide minerals or middlings containing valuable non-ferrous metals such as nickel, cobalt, and copper. This process uniquely operates without relying on specific reagents as pyrrhotite depressants, instead utilizing the natural pulp environment created by mild steel grinding media during the grinding step. The concentrate from the flotation stages, where the REDOX potential exceeds a predetermined value, is recycled back to the grinding step or earlier flotation stages for further processing.
The second patent focuses on a selective flotation process that improves the separation of mono/multi-metallic sulphide minerals from significant amounts of iron sulphides, primarily pyrrhotite. This process involves a conditioning stage with water-soluble sulphur-containing inorganic compounds, followed by further conditioning with nitrogen-containing organic chelating agents, such as polyethylenepolyamines. This innovative approach allows for the selective recovery of valuable non-ferrous metal minerals while effectively depressing iron minerals.
