Title: The Innovations of Donald H Eberts
Introduction
Donald H Eberts is a notable inventor based in Scarborough, Canada. He has made significant contributions to the field of metallurgy and liquid-liquid contact processes. With a total of 2 patents, Eberts has demonstrated his expertise and innovative thinking in his area of specialization.
Latest Patents
Eberts' latest patents include a process for the hydrometallurgical production of zinc oxide from roasted zinc. This innovative process allows for the extraction of high-quality, high surface area zinc oxide from roasted zinc sulphide concentrate. The method involves leaching with an ammoniacal ammonium carbonate solution and includes optional preliminary oxidation and water leaching steps to remove soluble impurities. Additionally, an optional aqueous sulphur dioxide leaching step is utilized to selectively remove readily soluble zinc oxide. The process also features an improved source of roasted zinc sulphide concentrate and an optional reduced pressure calcining step to enhance the surface area of the produced zinc oxide.
Another significant patent by Eberts is related to a liquid-liquid contact apparatus. This invention facilitates the mixing of two liquid phases supplied at steady flow rates. The system compensates for variations in the supply rates by pumping each liquid at a constant flow rate higher than the maximum flow rate provided by the supply. This allows for the recirculation of disengaged phases as necessary to meet system demands.
