A New Process for Co-Ni Separation – ALTA 2010 2 ABSTRACT A new process has been developed jointly by CSIRO and CESL, for separating cobalt from nickel in an impure leach solution. The process uses synergistic solvent extraction (SSX) with commercially available reagents, but in a novel and efficient manner using kinetic factors.

The overall economics and suitability of the process relies on the total nickel recovery, whereas the flotation performance should be assessed on the recoverable nickel, which is approximately 80% of the total nickel.

A South American nickel mine has been producing a nickel concentrate that also contains copper and iron (15 percent nickel, 5 percent copper, 28 percent iron) for the end use of stainless steel production. A critical specification for the quality of the steel is the iron to magnesium oxide ratio (Fe:MgO), with a ratio of below 3.5:1 having a substantial impact on the nickel value. This nickel ...

A process for the beneficiation of nickel bearing laterite ores by means of froth flotation wherein a dispersed pulp of the ore is conditioned with a fatty acid type collecting agent either at an elevated pH to produce, following flotation, an enriched flotation tailing or at a reduced pH to produce, following flotation, an enriched flotation ...

Bulk flotation An efficient procedure for nickel recovery is to combine copper sulphate to activate pentlandite with guar gum to depress talc. This is the method which has been used for the flotation of nickel ores in industry and which we have termed the "standard bulk float". A selection of results for this ore is given in Table 3.

Various processes are used to treat nickel matte. One process is the ammonia pressure leach, in which nickel is recovered from solution using hydrogen reduction, and the sulfur is recovered as ammonium sulfate for use as fertilizer.In another, the matte may be roasted to produce high-grade nickel oxides; these are subjected to a pressure leach, and the solution is electro- and carbonyl refined.

This problem can be overcome by using depressants like car-boxymethylcellulose (CMC) and guargum deriva-tives, although their cost accounts for as much as 60% of the reagent cost incurred in the plant.
