many precious metals from this ore, cobalt is not recovered yet. This metal occurs as an accompanying element, mostly in the form of cobaltite (CaAsS), with the average content of 50-80 g/Mg.

Mihaylov et al. (2000) have developed a novel hydrometallurgical process for nickel and cobalt recovery from the Goro laterite ore. Their study proposed the simultaneous extraction of 0.6 g/L Co and 6 g/L Ni from 3 g/L Mn and 10 g/L Mg sulphate solutions by 15% Cyanex 301, at an aqueous to organic phase ratio A:O = 2.5.

This residue contained 0.28 pct of the copper, and 79 pct of the cobalt and nickel from the original 25.2-kg batch of concentrate. Using a higher grade feed containing 1.2 pct Ni, the recovery of nickel and cobalt was 88 pct at grades of 16.2 and 11.4 pct, respectively. In each case, 99.7 pct of CuFeS2 was dissolved.
The nickel and cobalt content (0.22 % and 0.0055 %, respectively) in Olivine are too low to apply this technology based on the current nickel and cobalt price and carbon tax level. The increase of 0.1 % in nickel content to 0.3 % or higher nickel recovery (e.g. faster kinetics at higher NTA dosage) may make the process profitable.
Cobalt is a fairly common element in Earth's crust, averaging about 17.3 ppm (Rudnick and Gao, 2013), which ranks it as element no. 33 in terms of crustal abundance (Cobalt Development Institute, 2016a).Cobalt is found in relatively high concentrations in mafic and ultramafic igneous rocks (Table 1).The Ni/Co ratio decreases from ultramafic …
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. It is applicable to dilute nickel leach liquors containing ...
A comparative analysis of the evolution of ore grades, energy costs, and market prices was additionally carried out. According to the simulations, extracting nickel from sulfide ore tailings would be profitable if the price doubled. As for Cobalt, it would only be feasible if the market price increased considerably.
