Obtaining metals from this ore is much easier. For example, Haematite ore ( Iron) and Bauxite ore (Aluminium) Sulphide Ores- In this particular ore, the metals are present in the sulphide form. Since it is difficult to extract metals from this ore, they are usually converted to oxides with the process of metallurgy.
