     · The final outcome of the two processes is the conversion of an ore into an oxide ore. Roasting is the process of heating the ore in the presence of air. It involves gassolid reactions that take place at very high temperatures. Calcination is heating to high temperatures in air or oxygen. However, the amount of air or oxygen here is limited.

    Mixed oxide phases—that is, perovskites or spinels such as titanates or ferrites—are also produced in a calcination process in which the oxides react. The calcination process is also markedly influenced by the prevailing atmosphere. The calcination of hydrous oxide gels differs from that of the crystalline precursors only in the early stage.
