D
None of the above
Explanation: 

Detailed explanation-1: -Nickel reserves and resources Economic concentrations of nickel occur in sulphide and in laterite-type ore. Rich deposits are found in Australia, Indonesia, South Africa, Russia and Canada, which together account for more than 50% of the global nickel resources.

Detailed explanation-2: -Sulfide ores are crushed and ground in order to liberate nickel minerals from the waste materials by selective flotation. In this process, the ore is mixed with special reagents and agitated by mechanical and pneumatic devices that produce air bubbles.

Detailed explanation-3: –In India, Nickel occurs as oxides, sulphides and silicates. It is found as oxide in Odisha which has 93% of the India’s nickel resources. In Jharkhand, nickel is found along with copper and uranium deposits. However the exact extractable amount of nickel reserves is uncertain.

Detailed explanation-4: -In Nickel Flash Smelting technology, sulfide nickel concentrate is processed in the Outotec® Flash Smelting Furnace to produce nickel matte and slag. The matte is transported to the Peirce-Smith converters where it is blown to high-grade matte.
