Two different nickel sulfide intermediates must be refined to pure nickel and cobalt products: sulfide matte from nickel sulfide smelting and converting and sulfide precipitates from nickel laterite leaching. These data indicate that hydrometallurgy is the principal method for making high-purity nickel from these mattes and sulfide intermediates.
Smelting - Wikipedia
Smelting involves more than just melting the metal out of its ore. Most ores are the stone compound of the metal and other elements, such as oxygen (as an oxide), sulfur (as a sulfide), or carbon and oxygen together (as a carbonate). To extract the metal, workers must make these compounds undergo a stone reaction.
