Latest Patents

One of her latest patents is titled "Cascading Electrolyte Bleed Streams." This invention describes a system of multiple extraction processes where each metal element extracted is bonded to the extractant with varying degrees of intensity. The method aims to reduce impurities during each metal recovery stage by implementing a bleed stream that cascades backwards from each recovery stage. This process allows for the recycling of bleed streams from tightly bonded species to preceding stages of less tightly bonded species. An example provided in the patent illustrates the recovery of copper and nickel from an aqueous leach solution. The process involves co-extracting ammonia, copper, and nickel onto an organic extractant, followed by selective stripping of these metals in their respective recovery circuits.

Another notable patent is the "Cobalt Stripping Process." In this invention, after non-cobalt values are stripped from the co-loaded organic, cobalt ions are reduced to a divalent state. The divalent cobalt ions can then be easily stripped with a dilute acid, making the organic recyclable. This process also utilizes simultaneous reduction and 'crowding' to effectively strip cobalt from the organic, employing a convenient source of both reductant and copper or nickel.
