    So, what's your interpretation, Tenner? (And TY for going to the trouble and sharing!)

    Two quite different methods: Caustic Leaching vs Alkalai Leachng but with the same product outcome... namely, Purity of 99.97%C.

    So, how is Michael Chan's the "Improved Method"? Is it more environmentally friendly than the Christoph Frey's or an improved version of a traditional alkalai leaching method? And, how does this fit in with EGR's mission to get our technologies patented?
