Moreover, the element can be extracted from sulfidic and lateritic ores. For the sulfidic ore, nickel is extracted with electric and flash smelting, which is where the ore is placed in a furnace with pre-heated oxygen. For lateritic ore, it is extracted using conventional roasting, which removes moisture from the ore then a reduction furnace is ...

Nickel, generally as laterite, is extracted via open-pit down to 0.2%. Copper is extracted at grades as low as 0.15% to 0.2%, generally in massive open-pit mines in Chile, where the size of the resources and favorable metallurgy allows economies of scale. Materials typically extracted from open-pit mines include: Bitumen; Clay;

The rock must be completely molten or dissolved to enable the nickel to be extracted. As a result, laterite projects require a higher initial investment in capital equipment and face a higher marginal cost of production, due to the cost of melting or dissolving the ore. Moreover, most of the as-yet-undeveloped laterite deposits are located in ...
