Oxidative precipitation recovers nickel and cobalt from ore

Most existing process plants for nickel laterite ores use intermediate precipitation processes to recover the nickel and cobalt from the leach solution. The precipitation produces an intermediate product of nickel and cobalt, either as mixed sulfide precipitate (MSP) or mixed hydroxide precipitate (MHP), while largely separating nickel and cobalt from impurities such as manganese, calcium and magnesium.

Figure 2. XRD analysis for Nickel Ore Nickel laterite was analyzed using XRF and XRD. The result of XRF was list - ed in Table 1. The table shows that the late- rite contains 0,514% of nickel, 0,04% of cobalt dan 1,776% of calcium. The nickel content found in this ore is classified as low grade, hence it called as limonite ore. This ore able to process using hydrometallurgy method.

Enhanced methods for nickel recovery from low-grade

Nickel and cobalt are converted to soluble sulfate salts, and are recovered from the slurry in a counter-current decantation circuit (CCD). CCD involves washing the residue and recovering soluble nickel and cobalt. The remaining acid is neutralized using a limestone slurry, which produces a gypsum precipitate.

JOM 0610: Cobalt-Its Recovery, Recycling, and Application

As shown in Figure Aa, the cobalt recovery process is based on the continuous selective oxidation and hydrolysis of cobalt from relatively impure nickel electrolyte. Cobalt-bearing slime, containing 8–10% Co, 28–34% Ni, 0.4–0.8% Cu, and 5–6% Zn, is treated by selective reduction with sulfur dioxide to solubilize the cobalt and nickel to thus separate them from the iron and some of the copper.

Treatment of Nickel-Cobalt Laterites

1. Nickel and cobalt can usually be solubilized from laterites using sulphuric acid at atmospheric pressure, just below boiling point. However, this generally requires a massive quantity of acid, which can render the process uneconomic. The main reason for this is that for limonitic ores in particular, the

Lateritic nickel ore deposits - Wikipedia

This ore is so rich in limonite (generally grading 47% to 59% iron, 0.8 to 1.5% nickel and trace cobalt) that it is essentially similar to low-grade iron ore. As such, certain steel smelters in China have developed a process for blending nickel limonite ore with conventional iron ore to
