Title: Emil H Nenniger: Innovator in Hydrometallurgical Treatment
Introduction
Emil H Nenniger is a notable inventor based in Oakville, CA. He has made significant contributions to the field of hydrometallurgy, particularly in the processing of electric arc furnace dusts. His innovative approach has implications for both environmental sustainability and resource recovery.
Latest Patents
Nenniger holds a patent for the "Processing of carbon steel furnace dusts." This process involves a hydrometallurgical treatment that utilizes an acetic acid leach. The acetic acid solution is designed to be strong enough to dissolve heavy metal residues found in the dusts. The iron-containing residues are then recycled back to a steel-producing furnace. Additionally, zinc and other heavy metals are precipitated from the hot acetic acid solution using hydrogen sulfide. The process also includes the precipitation of calcium as clean gypsum, which avoids leaving sulfate ions in the solution that could interact with the dust.
