Web1. Roasting It may be defined as the process of strongly heating a sulphide ore in the presence of air to convert it into metal oxide. For example, 2ZnS + 3O2 2ZnO + 2SO2 (Zinc sulphide + Oxygen → Zinc Oxide + Sulphur dioxide) 2PbS + 3O2 2PbO + 2SO2 Lead sulphide + Oxygen → Lead Oxide + Sulphur dioxide) Web4.6 Recall that the extraction of metals involves reduction of ores; 4.7a Explain why the method used to extract a metal from its ore is related to its position in the reactivity series and the cost of the extraction process, illustrated by: heating with carbon (including iron) Edexcel Combined science.
