Pyrometallurgical Process - an overview

In pyrometallurgical processes, e-waste is blended with other materials and incorporated into primary/secondary smelting processes (e.g., into Cu or Pb smelters) at 1200°C (Table 3.3). Cu smelting is the dominant route for e-waste recycling, where PMs are collected in Cu matte or black Cu.

23.2: Pyrometallurgy - Chemistry LibreTexts

2020-9-8  Thermodynamics of Pyrometallurgy The oldest, and still the most common smelting process for oxide ores involves heating them in the presence of carbon. Originally, charcoal was used, but industrial-scale smelting uses coke, a crude form of carbon prepared by pyrolysis (heating) of coal. The basic reactions are:

12.3 Primary Copper Smelting

2015-9-10  A typical pyrometallurgical copper smelting process, as illustrated in Figure 12.3-1, includes 4 steps: roasting, smelting, concentrating, and fire refining. Ore concentration is roasted to reduce impurities, including sulfur, antimony, arsenic, and lead. The roasted product, calcine, serves as a dried and heated charge for the smelting furnace.

Pyrometallurgy Metallurgy for Dummies

2021-1-19  The basic premise of most pyrometallurgical operations is simple: high-temperature chemistry is employed to segregate valuable metals in one phase while rejecting gangue and impurities in another phase. In most instances, both phases are molten (such as the matte and slag in a conventional copper smelting operation).

A Review of Recent Advances in Pyrometallurgical

2021-1-26  The Mintek’s ConRoast process, as shown in Fig. 26, is an alternative to matte smelting for the treatment of platinum group metal by reductive smelting in a DC arc furnace [35, 37, 39]. High PGM and base-metal recoveries can be achieved by reductive smelting of feed materials containing PGMs, using carbon as a reducing agent [ 36 , 37 ].
