Question

Name the two important ores of nickel. How is nickel extracted from its important ores?

Answer 1

Explanation:

Most of the nickel we use on Earth ismined from a number of nickel ores: pentlandite and pyrrhotite (iron nickelsulfides,the two most important nickel ores), garnierite (hydrous nickelsilicate), millerite (nickel sulfide), and niccolite (nickel arsenide).

Nickel: smelting, producing-Metalpedia Nickel is recovered through extractive metallurgy: it is extracted from its ores by conventional roasting and reduction processes that yield a metal of greater than 75% purity. ... First, copper is removed by adding hydrogen sulfide, leaving a concentrate of only cobalt and nickel.
