The mixture of iron and sulphur can be separated using the process of magnetic separation. Upon heating this mixture, sulphur undergoes melting before iron since the melting point of sulphur is very low in comparison to iron. and At a temperature of about 445 o C, the mixture ignites and eventually leads to the formation of sulphur …
