King River Resources Ltd (ASX:KRR) is making progress with test-work for a pre-feasibility study (PFS) into the production of high purity alumina (HPA) using its specially developed refining process at a proposed processing operation at Kwinana in Western Australia.
During the March quarter, HPA was produced at >4N (99.99%) purity by calcining high purity precursor materials purified by the company’s refining process.
The materials were refined from industrial chemical feedstock material available from domestic and international suppliers.
These >4N purity results are from five HPA production runs completed by Source Certain International (SCI), previously TSW Analytical Pty Ltd, and were calculated by the addition of all the assayed element impurities then subtracted from 100%.
Silver production set to record first annual rise in half a decade
