2020-8-20Solvent Extraction. CYANEX 272 extractant has proven to be the reagent of choice for the separation of cobalt from nickel from both sulfate and chloride media. It is used to produce a major portion of the worlds cobalt.
2009-8-26trial on the optimisation of the solvent-extraction process are presented. INTRODUCTION The flowsheet of Anglo Platinums Base Metal Refinery BMR Rustenburg, South Africa involves sulfuric acid leaching of sulfide smelter products followed by solution purification and electrowinning EW of nickel and copper 1, 2. At present, the only
The extraction process was performed in two stages. In the first stage, maximum copper extraction was targeted with nickel extraction minimized. During the second stage, nickel was extracted from the remaining copperfree aqueous solution and optimum experimental conditions for maximum nickel recovery were determined.
2011-10-15However, these methods show lower selectivity in the extraction of nickel and cobalt over iron. Therefore, the development of a new efcient extraction process for recovery of nickel and cobalt from laterite ores is still needed.
Nickel - Extraction and Purification - Mond Process. Mond Process. Purification of nickel oxides to obtain the purest metal is performed via the Mond process, which increases the nickel concentrate to greater than 99.99 purity. This process was patented by L. Mond and has been in industrial use since before the beginning of the 20th century.
The invention provides a method for extracting scandium from nickel laterite ores. The method includes carrying out leaching treatment on the nickel laterite ores by the aid of sulfuric acid to obtain leach liquor of the nickel laterite ores carrying out scandium-rich precipitation treatment on the leach liquor of the nickel laterite ores by the aid of first precipitants to obtain scandium ...

Sherritt Gordon Process. The nickel and cobalt metallurgy processes begin with an initial treatment of the mineral, re-concentrating it through crushing and flotationgravity and obtaining a speiss, rich in cobalt and nickel. The process begins by adding the sulfide-associated mineral to a reactor with sulfuric acid and pressurised air.
2015-11-20nickel in liquor, but currently the favoured process is the selective solvent extraction of cobalt away from nickel, using phosphinic acid derivatives, e.g. Cyanex 272. Although this extractant works well in pure solutions, unfortunately it also extracts many other metals commonly found
The nickel raw solution coming from the leaching plant to cobalt extraction is cooled and washed with kerosene to prevent foreign organic substances from entering the extraction process. Cobalt extraction is carried out in sequential cobalt extraction cells, where the nickel raw solution flows countercurrent to the extraction solution.
