Latest Patents

One of Jennings' latest patents is a process for recovering aluminum from alunite. This improvement involves dehydrating the alunite in particulate form and removing sulfur and alkali metal compounds. The remaining residue, which contains aluminum values, is then digested with alkali metal hydroxide to convert these values into soluble aluminates. The process includes multiple stages of digestion, allowing for a higher recovery of aluminum compared to previous methods.

Another significant patent is the redox treatment of alunite ore. This method involves roasting the ore to eliminate water of hydration and then treating it in both reducing and oxidizing atmospheres. The process culminates in leaching with a weak base and extracting aluminum content using a mixture of sodium hydroxide and potassium hydroxide. This innovative approach results in the efficient precipitation of aluminum hydroxide.
