Ann: Nickel Discovery at East Laverton, page-41

Ummmm, nice try. How about quoting the entire article next time ya Wally!

In collaboration with the Sydney-based SME Direct Nickel, we are testing a new extraction process that could make millions of tonnes of untapped nickel laterite reserves economically viable.CSIRO and Direct Nickel have carried out full-scale testing of the process in a pilot plant at CSIRO Perth. © Damien Smith Direct Nickel has developed a more cost-effective and efficient way to extract nickel from laterites using small amounts of nitric acid.About 95 per cent of the nitric acid can be recycled and re-used as a processing reagent, which vastly reduces the amount of waste produced and avoids the costly neutralisation and disposal of used acid.With only a few kilograms of nitric acid used per tonne of laterite compared to at least half a tonne of sulfuric acid per tonne, this new method offers a more environmentally sustainable and cost-effective processing option.To facilitate the transition from laboratory-scale to industrial-scale processing a mineral processing CSIRO invested in a pilot plant at our Waterford site (Perth), for large-scale testing of the new method. The new process has been successfully demonstrated at pilot scale.
