A study into the behaviour of nickel, cobalt and metal

2021-6-1  A key step in the hydrometallurgical processing of nickel laterites is the partial neutralisation of the leached slurry or pregnant leach solution (PLS) to neutralise free sulfuric acid (H 2 SO 4) and precipitate ferric iron [Fe(III)], aluminium (Al) and trivalent chromium [Cr(III)].The removal of these metallic impurities is critical for downstream recovery and refining of Ni and

Precipitation of impurities from synthetic laterite leach

2010-7-1  Before nickel and cobalt refining, neutralisation is commonly conducted to remove impurities such as chromium, iron, aluminium, arsenic, copper and silicon because they either interfere with the refining process or affect the purity of the nickel and cobalt final products.

Synthesis of N-(2-ethylhexyl)-pyridine-4-carboxamide and

To separate nickel and cobalt from leaching solutions containing such impurities, co-precipitation and re-leaching methods are typically used, which are very complicated and expensive processes as evidenced by the Murrin and Bulong projects for nickel laterite processing in Australia .
