Extraction of Metals

Extraction by electrolysis potassium, sodium, calcium, magnesium, aluminium
Extraction by reducing agent-carbon/carbon monoxide zinc, iron, lead
What’s in the charge? Iron ore (haematite = iron oxide and sand), limestone (mainly Calcium Carbonate), Coke (almost pure carbon)
Stage one: Reactions in the blast furnace Coke burns, giving off heat, C + O2 = CO2
Stage two: Reactions in the blast furnace Carbon monoxide is made, C + CO2 = 2CO
Stage three: Reactions in the blast furnace Iron oxide is reduced, Fe2O3 + 3CO = 2Fe + 3CO2
Limestone is for? reacting with silica, to remove impurities from the haematite, slag at the top is drained off
Waste gases? CO2 and Nitrogen
Extracting Aluminium bauxite to alumina/white aluminium oxide to electrolysis to usage
Electrolysis of Aluminium Alum. gains electrons at the cathode whilst, at the anode, the oxygen loses electrons
