A metal is obtained from its carbonate ore by converting it into its oxide by the process of Calcination. In Calcination, the ore is heated to a high temperature in the absence of air. ZnCO 3 s heat ZnOsCO 2 g. The metal oxides obtained by calcination are converted into the free metal by using reducing agents like carbon, aluminum which depend upon the reactivity of the metal.

The process is very effective in routinely producing gold purities in excess of 99.95. This process is economical from the point of view that it is inexpensive to operate and is fast and, with experience, very little gold deports to the slag, resulting in low metal inventory or lockup. Chapter 34 discusses the Miller process in more detail. 2.2.
