Latest Patents

Joseph S. Fox's latest patents focus on the recovery of chromium compounds from various sources. One of his notable inventions is the method for the recovery of high purity Cr₂O₃ from a chromium-bearing solution. This process involves producing (NH₄)₂CrO₄ through solvent extraction, evaporating the resulting aqueous solution, and igniting the solids to obtain high purity Cr₂O₃.

Another significant patent relates to the processing of chromium ore. This method allows for the recovery of chrome hydrate or high purity Cr₂O₃ from chromium ores by roasting the ore with Na₂CO₃ and CaO. The subsequent water leaching of the roasted mass leads to the precipitation of aluminum impurities, which are then removed. The leach liquor is treated with sulfur and NaOH to reduce chromium valence states, ultimately creating a chrome hydrate precipitate. The result is dried and calcined to yield a high purity Cr₂O₃.
