Title: Innovations of Kelvin Richard Buban
Introduction
Kelvin Richard Buban is an accomplished inventor based in Fort, California. He has made significant contributions to the field of metallurgy, particularly in the recovery of copper from complex process feeds. His innovative approach addresses the challenges associated with arsenic-containing materials, showcasing his expertise in chemical engineering.
Latest Patents
Kelvin holds a patent for a process titled "Recovery of copper from arsenic-containing process feed." This process involves the recovery of copper from a feed that includes base metal sulphidic components, iron, copper, and arsenic. The method utilizes a pressure oxidative leaching step with a partial pressure of oxygen above 200 kPa. This process generates free sulphuric acid, which solubilizes copper and other metals as aqueous sulphate compounds while precipitating arsenic as solid iron arsenic compounds. The treated slurry is then processed to separate the liquid phase containing sulphuric acid and copper sulphate from the solid iron arsenic compounds. To enhance stability and minimize arsenic re-dissolution, parameters such as temperature, free acid level, and residence time are carefully controlled. Ultimately, copper metal is recovered from the separated liquid phase.
Career Highlights
Kelvin is currently employed at Sherritt International Corporation, where he continues to apply his innovative techniques in metallurgy. His work has not only advanced the field but has also contributed to more sustainable practices in metal recovery.
