Solid minerals contributed immensely to the economic development of Nigeria in the pre-independence years. During this period, Nigeria was known for the production of coal as an energy source for electricity, railways and also for export. Tin, Columbite, Lead and Zinc were exported. Nigeria was the largest producer of Columbite at one point.
