Question

an ore gave sulphur dioxide on heating in air.outlinex the principle in extraction of metal from such a ore​

Answer 1

Explanation:

This forms froth which contains the pure ore . The ore thus obtained then goes through the process of roasting, where the ores are heated at very high temperature with exposure to oxygen. The sulphide ions of the ores form SO2 and metallic oxide. The metallic oxide then heated with carbon monoxide gives the metal.
