HPAL: Upping The Pressure
There are two limonite streams – Low grade (1.0-1.2% Ni) is sent to the HPAL plant, while a high Fe feed (0.6-0.9% Ni, 48-50% Fe) is exported to be made into low grade NPI/PI. Plant Capacity: Originally 30ktpa, the plant was expanded in 2017 to 36ktpa Ni in the form of a mixed sulfide product containing 55-60% Ni.

Processing – Karara Mining
Magnetite. Karara comprises a large-scale, long-life magnetite orebody amenable to bulk mining and processing. Magnetite ore has lower iron content (34-36% Fe) than hematite ore (58-64% Fe). It must be upgraded by a complex ore treatment process (beneficiation) to produce a high-grade (+65% Fe) concentrate for steelmaking.

Challenges in processing nickel laterite ores by flotation
It should be added that segregation of laterite ores prior the flotation process has shown some improvement in upgrading nickel. The segregation process relies on the addition of calcium chloride or sodium chloride and carbon allowing the formation of nickel and iron chlorides at temperatures between 900 and 1150 °C. Iwasaki et al., (1961) and …
