How Pentlandite is Processed for Uses in Our Lives

What is pentlandite?

Pentlandite?is a sulfide of nickel and iron that is bronze-yellow in color and has a metallic luster. Pentlandite?is the main mineral raw material for refining nickel.

?

The Mohs hardness of pentlandite is 3.5-4, the specific gravity is 4.6-5, and it is non-magnetic. The streaks are usually a light bronze brown. Pentlandite?usually coexists with various minerals such as chalcopyrite, pyrrhotite, and magnetite.

Processing of pentlandite

Crushing: The mined raw ore is sent to the jaw crusher?through the feeder for coarse crushing, and the crushed materials then enter the?cone crusher for secondary crushing. After passing the screening equipment, it enters the grinding process, and the unqualified minerals enter the cone crusher again for crushing.

Grinding: Qualified minerals enter the ball mill?and are ground into mineral powder, and then sent to the spiral classifier?for sorting.

Flotation: Mixed flotation can be used to separate copper-nickel minerals from pentlandite while removing impurities. The minerals are then separately flotated to select copper concentrate and nickel concentrate.

?

Drying: The mineral after flotation is dehydrated by concentrator first, and then dried into mineral powder by dryer

Applications of pentlandite

Nickel is an important alloy, widely used in radar, aircraft and other military manufacturing. It can be used in the production of stainless steel to improve the corrosion and heat resistance of the product. It can also be used in battery manufacturing, suitable for laptops, electric cars, and has environmentally friendly features. Nickel oxidation is slow and can be used to electroplate the surface of objects to meet aesthetic needs.
