Extracting metals with charcoal | Resource | RSC Education
The reactions confirm the place of carbon in the reactivity series, above lead and copper, as it reduces the metal oxides to the metals and is itself oxidised to carbon dioxide: CuO(s) + C(s) → Cu(s) + CO 2 (g) and PbO(s) + C(s) → Pb(s) + CO 2 (g).

Copper oxide + carbon → copper + carbon dioxide. 2CuO(s) + C(s) → 2Cu(l) + CO 2 (g) Copper oxide is reduced. as carbon is oxidised, so this is an example of a redox. reaction.
Copper Smelting Chemistry Tutorial
The concentrated (enriched) ore can contain up to 35% copper and a number of impurities such as antimony, arsenic, and lead. Roasting : reduces impurities in the copper ore and produces calcine (a mixture of products) * Concentrated (enriched) ore is heated to between 500 o C and 700 o C in air.

An Introduction to the Chemistry of Metal Extraction ...
Instead, the usual ore of aluminum is bauxite - which contains from 50 - 70% of aluminum oxide. Copper is much rarer, but fortunately can be found in high-grade ores (ones containing a high percentage of copper) in particular places. Because copper is a valuable metal, it is also worth extracting it from low-grade ores as well.

Thus, neither carbon nor hydrogen is a suitable reducing agent for metal sulphides. Aluminium cannot be used, as reaction with metal sulphide would produce aluminum sulphide, which is not so exothermic. So, sulphide ores are preferentially converted to oxide ores as any reduction method (reduction by C, H 2, AI etc.) could then be conveniently ...
Oxide ores cannot be reduced by carbon. Why? - Quora
*Firstly , reduction of oxide ores of metals with carbon requires a very high temperature. For example:-2 Al2O3 + 3C= 4Al+3CO2 (at 5000°c). *Secondly , at this high temperature the metal will react with carbon and form metal carbide and evaporate ...
Carbon Reduction Method Chemistry Tutorial
Carbon is oxidized from elemental carbon to an oxide of carbon in which carbon is in a positive oxidation state (has a positive oxidation number). Example: Extracting Lead from Cerussite. Mining : digging or blasting to obtain the lead ore from the surrounding rock; Crushing : mined lead ore is crushed into very small pieces
The Extraction of Copper - Chemistry LibreTexts
Extracting of Copper from Other Ores. Copper can be extracted from non-sulfide ores by a different process involving three separate stages: Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulfuric acid to produce a very dilute copper(II) sulfate solution.
