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.

The process begins by adding the sulfide-associated mineral to a reactor with sulfuric acid and pressurised air. This procedure removes the sulphides to obtain nickel (II) sulfate and cobalt (II) sulfate in solution. In this first dissolution stage, the sulfide is removed. NiS + 2O2 NiSO4. CoS + 2O2 CoSO4.
cobalt processing, preparation of the metal for use in various products.. Below 417 °C (783 °F), cobalt (Co) has a stable hexagonal close-packed crystal structure. Of the three common ferromagnetic metals (iron, nickel, and cobalt), cobalt has the highest Curie point (that is, the temperature above which its magnetic properties are weakened). It is unique in that, added in moderate amounts ...

The economic and environmental advantages of AeRD for processing of laterite tailings comprise no requirement for an anoxic atmosphere, 1.8-fold less acid consumption than for AnRD, as well as nickel and cobalt recovered in a ferrous-based pregnant leach solution (PLS), facilitating the subsequent metal recovery.
This residual material must be removed to avoid precipitation in subsequent solvent extraction for copper and cobalt recovery. Tests were conducted on a composite batch of filtrates from several jarosite precipitation tests containing, in grams per liter, 1.25 As, 7.85 Co, 5.9 Cu, 1.95 Fe, and 0.39 Ni. The solution pH was 1.5.
Cobalt Recovery (from concentrate) % 94.5 Concentrate mineralogy has considerable impact on equipment sizes, impurity loads and flowsheet design. Table 2 and Table 3 show the mineralogy and elemental assays of the concentrate used in the conceptual study. The major nickel bearing mineral is pentlandite with a smaller portion of nickel

A review has been completed of current and proposed processing technologies for nickel laterite ores. Although future supplies of nickel depend on laterite ores, their processing is inherently energy intensive and expensive as, unlike sulphide ores, they cannot be significantly upgraded, meaning the entire ore needs to be treated in the process. In addition, hydrometallurgical processes in ...

The key to the Process is the use of nitric acid as the leaching agent and the subsequent use of a patented recovery and recycling process returning +95% of the nitric acid for re-use. See below in Figure 1. The ore is mined and then fed to a comminution plant for crushing to ‹2mm.
The extraction of nickel process generally consists of crushing, sieving, washing, re-selection, grinding, and slurry concentration, or the nickel leaching method. The target element nickel distribution varies with the nature of the ore, mostly contained in fine-grained grades. For example, the nickel minerals of the Ramu laterite mine in Papua ...
In nickel smelting, most of the cobalt is recovered during electrolytic refining of the nickel by precipitation from solution, usually as a cobaltic hydroxide. But even in nickel smelting, cobalt starts to oxidize before the nickel and can be recovered from the final converter slag.
