Ann: Very High Metallurgical Recoveries, page-255

thanks for sharing, still getting across all the REE clay plays so good to have another one to look into.

So hydrochloric acid again for an Esperance clay, but ANSTO have tested sulfuric for IXR, KTA, ITM, AR3, there must be something different in the minerals in Esperance that needs HCl? I wonder what organic acid they will trial, haven't seen many mining projects using organic acids before, ANSTO definitely the experts in this space they have done hundreds of tests for Aussie REE clays now across all these projects.
