اقرأ أكثرOn the basis of their time of formation relative to the host rock, the ore deposits are divided into two groups: (i) Syngenetic and (ii) Epigenetic. (i) Syngenetic deposits are such deposits that have formed simultaneously with the enclosing rock. These are either of igneous or of sedimentary types.

Nearly all rock deposits contain some metallic minerals, but in many cases the concentration of metal is too low to justify mining the ore. Ores are usually found concentrated in deposits with a definite gradation of metal concentration from the ore to the surrounding rock. The ore often ...

The most common iron ore minerals are hematite, lepidocrocite and goethite while the most common manganese ore minerals are braunite, manganite and hausmannite. These deposits are believed to have formed in shallow marine basins and are confined to Proterozoic rock sequences.
