Hydrometallurgy of Nickel; The high temperature (~250°C) acid pressure leaching of nickeliferous laterite ore has been practised commercially since the late 1950's. The acid pressure leach solution is treated using hydrogen sulphide to produce a high grade sulphide containing at least 50% nickel. This mixed sulphide is then pressure leached to .

Cobalt extraction - Wikipedia

Nickel-cobalt lateritic ores can be treated by either hydrometallurgical processes or pyrometallurgical processes, such as matte or ferronickel smelting, which require the entire ore to be melted and the metal values to be separated from the residual components of the ore. The hydrometallurgical process for laterite ore can use sulfuric acid or ammonia leach solutions.
