The significance of this highly successful application of colloid science and its importance to future mineral development has required rigorous and competent independent checking at all stages. Reports and comments by thirty-eight leading colloid chemists, geologists, and exploration managers, endorsement of the Australian Government and seven Australian scientific institutions as indicated by their logos are set out in the verification reports accompanying the e-book and are available by clicking here. Read these comments by senior scientists first if your own experience interpreting problematic geological observations is limited.
