In the case of limonite, and as an alternative to RKEF, hydrometallurgical technologies such as High-Pressure Acid Leaching (HPAL) can be applied to process nickel through collection of its precipitates, e.g. from Mixed Hydroxide Precipitates (MHP) containing nickel (and also iron). MHP can be refined to give Class 1 nickel products, or it can ...

Saprolites are formed beneath the limonitic zone and are rich in magnesia and silica. These ores are typically processed via the rotary kiln, electric furnace (RKEF) process to produce Class II nickel products including ferronickel (FeNi, typically 20–40% Ni) and nickel pig iron (NPI, typically 8–12% Ni).
