Title: Innovations by Donald A. Douglas: A Pioneer in Metal Recovery Techniques
Introduction
Donald A. Douglas, a remarkable inventor based in Amherst, NH, has made significant contributions to the field of metallurgy with five innovative patents to his name. His groundbreaking work focuses on the recovery of refractory metals and the efficient processing of scrap alloys, leading to advancements in sustainable materials management.
Latest Patents
Among his latest patents, one notable innovation is the "Partitioning of refractory metals from oxidation resistant scrap alloy." This process involves treating alloy scrap containing refractory metals like chromium, molybdenum, tungsten, and others, alongside base metals such as nickel and copper. By calcining the scrap at a temperature range of 800°C to 1150°C in the presence of an oxygen-containing gas and specific alkali metal salts, Douglas's invention allows for the conversion of refractory metals to alkali metal molybdates, tungstates, and more, ultimately facilitating the recovery of these valuable metals through hydrometallurgical techniques.
Another significant patent is centered around "Chromium recovery from scrap alloys." In this process, Douglas details a method of recovering chromium, vanadium, molybdenum, and tungsten from alloy scrap. The technique employs calcination with sodium carbonate, which transforms refractory metals into water-soluble forms and base metals into insoluble oxides. This innovative approach minimizes energy consumption while enhancing recovery rates, proving to be both economically and environmentally beneficial.
