Latest Patents

Donald J. Mayhall holds a patent for a metallurgical process using liquid fuels. This process involves a lateritic ore reduction technique that employs a light, low sulfur-containing naphtha to produce a pre-reduced calcine. Additionally, a heavy residual fuel is utilized to provide the energy necessary to melt the calcine. Notably, both operations are conducted at a location remote from the source of the required fuels. The process includes mixing two different fuels at the source to create a blend, which is then pumped through a single pipeline to the ore reduction plant at ambient temperature. The blend is fractionated into two products needed for various operations in ore treatment, ensuring that the fuels are consumed substantially in their entirety in their respective operations.
