Answer» Solution :Silica act as flux in the metallurgy of `CuSiO_(2)+FeOrarrFeSiO_(3)` and Gyolite is going to decrease the MELTING point of melt or MIXTURE. CALCINATION is heating are in limited supply of oxygen/air, while roasting is heating are in a regular supply of air in a FURNACE at a temperature below the melting point of the metal. |
