In vd tb on pg 138 in definition of roasting it says : Roasting is the process of heating the conc ore in the presence of excess air to a high temperature before it is reduced to a METAL. I think writing metallic oxide instead of metal would be appropriate. Do u think so? But going against book can also cause a problem. |
