Title: Edwin L. Owen: Innovator in Manganese Recovery and Metal Extraction
Introduction
Edwin L. Owen is a notable inventor based in San Antonio, TX (US), recognized for his contributions to the fields of manganese recovery and metal extraction. With a total of 3 patents to his name, Owen has developed innovative processes that enhance the efficiency of metal recovery from various sources.
Latest Patents
One of Owen's latest patents is focused on the flotation and sintering of synthetic manganese carbonate. This process involves recovering manganese from manganese nodules after the treatment of base metals such as copper, nickel, cobalt, and molybdenum. The method includes reacting the manganese in the nodules to yield a carbonate, which is then subjected to flotation. The resulting manganese carbonate froth is collected, dried to produce a concentrate, and sintered to create synthetic manganese oxide. The patent also discusses the effects of reagent dosage, pH control, and temperature on the yield of the synthetic manganese oxide.
Another significant patent by Owen is the cascading electrolyte bleed streams system. This innovative approach involves multiple extraction stages where each metal element is bonded to the extractant with varying degrees of intensity. To minimize impurities during metal recovery, a bleed stream from each stage is cascaded backward to earlier stages. This method is exemplified in a process for recovering copper and nickel from an aqueous leach solution, where ammonia, copper, and nickel are co-extracted onto an organic extractant. The process ensures that impurities are effectively managed, enhancing the overall efficiency of metal recovery.
