Metals US Had a nice chat with the folks at Metals US. The extraction units are quite small..about 3 feet in diameter. Any metal that can be processed in solution can be separated. It is an ion exchage type technology..very much like a water softener that takes out calcium carbornate. They are working on the BHS large sample. I don't know when the 1 tonne sample was received by Metals US. It hade not shipped when we did the site visit on June 9th. If Metals US has a booth at the AEMA Conference in Spokane in Dec. we will hook up to better understand how this process works. CP
