Pyrometallurgical Process an overview ScienceDirect Topics

Roasting, smelting, and converting are pyrometallurgical process steps that are based on the relative affinities of metals for sulfur and oxygen. A typical process flowsheet is shown in Fig. 1.Iron sulfide is primarily converted to oxide in roasting. When only about half the iron is oxidized during roasting, less nickel and copper sulfides are oxidized.

Pyrometallurgy

Pyrometallurgy is a branch of extractive metallurgy. It consists of the thermal treatment of minerals and metallurgical ores and concentrates to bring about physical and chemical transformations in the materials to enable recovery of valuable metals. Pyrometallurgical treatment may produce products able to be sold such as pure metals, or intermediate compounds or alloys, suitable as feed for further processing. Examples of elements extracted by pyrometallurgical processes include the oxides of less reactive ele

Pyrometallurgy an overview ScienceDirect Topics

Industrial grade pyrometallurgy is usually direct put the WPCBs containing 5%–40% copper into the blast furnace, and the product is black copper containing 70%–85% copper. The black copper is then poured into the converter, which makes an oxidizing slag of Pb, Zn, and Sn, and the copper that contains 95% copper
