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 content.

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 Wikipedia

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

COPPER Copper production Repository

About 80 % of primary copper production comes from low-grade or poor sulfide ores. After enrichment steps, the copper concentrates are usually treated by pyrometallurgical methods. Generally, copper extraction follows the sequence (see Figure below): 1. Beneficiation by froth flotation of ore to give copper concentrate

Primary Metal Production

General Principles of Production of Metals by Pyrometallurgy In pyrometallurgy, metals are extracted by converting sulfides into oxides and then reducing oxides into metals, using carbon or carbon monoxide as reducing agents. The reactions for lead, zinc, and iron are given below. The reader is cautioned that the following chemical reactions are
