nickel ore for processing ferronickel

The nickel is present as nickel silicate minerals such as garnierite MgNi 3 Si 2 O 5 OH 4 Nickel may also be present in other forms such as nickel–talc and nickel–sepiolite The product is refined ferronickel which contains 20–40 Ni and 80–60 Fe The ferronickel is suitable for making stainless steel and other ferrous alloys

In this process the ore is mixed with special reagents and agitated by mechanical and pneumatic devices that produce air bubbles As these rise through the mixture the sulfide particles adhere to their surfaces and are collected as a concentrate containing 6 to 12 percent nickel
