Title: The Innovative Contributions of Donald Roderick McKay
Introduction
Donald Roderick McKay is a notable inventor based in Rossland, Canada. He has made significant contributions to the field of metallurgy and sulfur processing, holding a total of three patents. His work has had a profound impact on the efficiency and effectiveness of various industrial processes.
Latest Patents
One of McKay's latest patents is a "Process for the melting of sulfur." This innovative method involves circulating molten sulfur through a mixing device in a spiral flow, creating a continuous vortex. This vortex allows for the feeding of particulate solid sulfur, with or without moisture, into the molten sulfur. The process effectively evaporates any associated moisture, resulting in molten sulfur that is substantially free of moisture.
Another significant patent is the "Process for hydrometallurgical upgrading." This invention pertains to the treatment of concentrates of various sulfides, including copper, nickel, cobalt, lead, and iron. The process involves subjecting a finely ground slurry of a sulfide concentrate to an oxidation leach at elevated temperatures and pressures. This method preferentially leaches cobalt and nickel while converting galena to lead sulfate. The resulting mixture undergoes differential flotation to obtain lead and copper concentrates, showcasing McKay's innovative approach to metallurgy.
