Is the replacement of a 130yr standing metallurgical process not a paradigm shift?
Is the determination that not only bauxite and nepehelines are the source rocks for profitable alumina extraction, but to bring in aluminous clays not a paradigm shift?
Is the extraction of those numerous products from clays using one process and with no tailings and with acid recirculation not a paradigm shift?
Are not the resulting production costs levels for each of those numerous products not a paradgim shift?
If none of the above is a paradigm shift, are not all of them (and more possibly) together as a whole, not a paradigm shift?
