Metal Extraction via Oxide Reduction
What you need to know
Explain the concepts of reduction and oxidation specifically in terms of the loss or gain of oxygen.
Identify which chemical species are oxidised and which are reduced in a given reaction based on the transfer of oxygen.
Recall that most metals are found in the Earth as metal oxide compounds that require chemical reduction reactions for extraction.
Explain the principles of industrial metal extraction using the position of carbon in the reactivity series.
Understand that metals less reactive than carbon can be economically extracted from their oxides by reduction using carbon.
Interpret and evaluate information about specific non-ferrous metal extraction processes, explaining why certain metals are extracted with carbon and others are not.
