A bulk core sample from the Blackbush deposit was leached using an acidified seawater solution and the dissolved uranium was then recovered from the leach solution using two different resins.
The two resins were then separately stripped of uranium and a yellowcake product, which had high grade containing 85% uranium metal.
The results contains an initial proof-of-concept for the extraction of uranium from typical mineralization into acidified saline solution, extraction of the dissolved uranium from acidified hyper saline solution to resins, stripping of uranium from resins; and the precipitation of a uranium yellowcake product.
The uranium was stripped from the resins using conventional reagents and methods and a peroxide product precipitated.
