Latest Patents

Kekesi's latest patents include innovative methods for producing high purity cobalt and high purity cobalt targets. His patents detail a process where cobalt containing impurities, such as copper, is dissolved in a hydrochloric acid solution. The concentration of the hydrochloric acid is carefully adjusted to between 0.1 kmol/m to 3 kmol/m. Cobalt is then added to the solution, and an inert gas is injected while agitating the mixture. This process converts divalent copper ions into monovalent copper ions. The solution is subsequently passed through a column filled with anion exchange resins, allowing for the separation of copper from cobalt. Finally, the aqueous solution is evaporated and heated in a hydrogen atmosphere to generate high purity cobalt.
