The segregation process as applied to nickel laterite ores involves the formation of gaseous nickel and iron chlorides which are subsequently reduced to form ferronickel on the surface of a solid carbon reductant. A fundamental study of the process has been carried out using limonite, nontronite and garnierite ores.

Genesis and types of nickel laterites. Lateritic nickel ores formed by intensive tropical weathering of olivine-rich ultramafic rocks such as dunite, peridotite and komatiite and their serpentinized derivatives, serpentinite which consist largely of the magnesium silicate serpentine and contains approx. 0.3% nickel. This initial nickel content is strongly enriched in the course of lateritization.

Nickel Ore is a common, naturally occurring ore found in asteroids and terrestrial planets. It has a shiny yellowish texture, almost like pirite/fake gold. Nickel can be processed in a Refinery to produce Nickel Ingots at a 40% ratio. Which is to say, 1000 kg of ore will produce 400 kg of ingots. Using a Refinery, 749 kg of Nickel Ingot can be produced per hour, without Speed or Yield Modules ...

The smelting of ferronickel using lean nickel ores usually starts with roasting (calcining) of the ore mixture with limestone (~one third of the ore), anthracite (~1/10 of the ore amount), and recycled dust. Roasting is carried out in rotary kilns (~3 m in diameter, ~75 m in length, with a hot zone length of 9 to 12 m in the case of lean ore ...
