23.2: Pyrometallurgy

At ordinary environmental temperatures, reaction 23.2.4 is always spontaneous in the reverse direction (that is why ores form in the first place!), so ΔG° of Reaction 23.2.4 will be positive. ΔG° for reaction …

Pyrometallurgy

Pyrometallurgy is the predominantly used technology for industrial e-waste treatment. In industrial pyrometallurgical processes for e-waste recycling, the scrap is usually fed into furnaces, where the load is smelted via flash or bath smelting. Subsequently, the conversion process takes place (Zhang and Xu, 2016 ).

the metal at the cathode. Pyrometallurgy oﬀers the advantage that a pre-treatment step beyond unit dismantling and shred-ding of the components is rarely required.31,44 The output from the smelter for electronic waste is best described as a copper bullion, due to the high copper content found in PCBs.

Computational Modeling in Pyrometallurgy: Part I

Pyrometallurgy is the subtle art and science of using high temperatures to process raw materials into valuable products. This is performed in several key stages, including pre-treatment, chemical reactions, separation of product and waste streams, and product refining. The interior of pyrometallurgical vessels in all stages is an extreme and ...

Pyrometallurgy | Britannica

pyrometallurgy, extraction and purification of metals by processes involving the application of heat. The most important operations are roasting, smelting, and refining. Roasting, or heating in air without fusion, transforms sulfide ores into oxides, the sulfur escaping as sulfur dioxide, a gas. Smelting (q.v.) is the process used in blast furnaces to reduce iron ores.
