Pyrometallurgy an overview ScienceDirect Topics

The nickel–copper-dominated sulfide concentrate is recovered through the extractive pyrometallurgical-process route by conventional roasting and reduction processes that yield a metal of greater than 75% nickel purity. Nickel with high purity can be used directly without further purification, depending on the composition of the impurities.

Copper: smelting, producing and classification-Metalpedia

Copper: smelting and classification; The smelting of copper; Copper that is mined from copper ore, after beneficiation, becomes high quality copper concentrate. Then, after being smelted, refined copper and copper products are yielded. There are two ways of smelting copper, one is pyrometallurgy, the other hydrometallurgical. Nowadays, the main smelting method is pyrometallurgy, which accounts
