Liquid-Liquid Extraction Column: Selection, Scale-up and Design. The extractor's separation performance is typically measured during the pilot plant test. It may be measured over an array of effective heights, solvent-to-feed ratios, and flow rates. It is useful to note that the agitation speed varies if the selected extractor is agitated.

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.
