Solution:
Manganese and iron oxide can be reduced by metal aluminium (Al) powder being more reactive than them to obtain the metal in a molten state.Manganese dioxide () is reduced by aluminium metal powder through an exothermic reaction receiving manganese in a molten state. Similar is the case with iron (III) oxide or ferric oxide (); since coke cannot reduce it, aluminium being more reactive reduces it, and molten iron is received. The equation for the reaction is:
