Unlocking millions of tonnes of nickel - CSIRO
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.

Process development for the direct solvent extraction of
2017-1-18 A direct solvent extraction (DSX) process for purifying nickel and cobalt from the nitric acid leach solution of nickel laterite ores was conceived and experimentally probed. The proposed process consists of two solvent extraction (SX) steps but with only one extractant — bis(2,4,4-trimethylpentyl)phosphinic acid (Cyanex® 272) — used in both steps. The first extraction step
