Calcination And Roasting What Is Calcination And Roasting

Aug 31, · Calcination involves thermal decomposition of carbonate ores. Roasting is carried out mostly for sulfide minerals. During calcination, moisture is driven out from an ore. Roasting does not involve dehydrating an ore. Carbon dioxide is given out during calcination During roasting large amount of toxic, metallic and acidic compounds are released.

Reading Classes of Minerals Geology

Reading Classes of Minerals. Minerals are classified according to their chemical properties. Except for the native element class, the chemical basis for classifying minerals is the anion, the negatively charged ion that usually shows up at the end of the chemical formula of the mineral. For example, the sulfides are based on the sufur ion, S 2. Pyrite, for example, FeS 2, is a sulfide mineral.
