Solid Mineral resources are the result of mineral and organic formations in the earth’s crust creation over millions of years starting with the first sources of the Earth’s origin.
It 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. The earnings from solid minerals were used to develop roads, education, hospitals, and develop the petroleum industry.
The decline of the solid minerals industry started with the discovery of oil to an extent that Nigeria became a mono product economy and vulnerable to international oil politics.
The neglect of the minerals in the industry led to disorder in the minefield with a strong presence of illegal miners whose activities are characterized by inefficient mining, illegal trading of highly priced minerals, severe ecological degrade, in, diseases, and huge loss of revenue to the government through smuggling.
An established and well managed solid minerals sub-sector will accelerate the economic, social, and political growth of Nigeria by the provision of gainful employment well-managed in national income earnings far exceeding the petroleum sector .
Solid minerals can provide the all-important launching pad for the development of other sectors of the economy as well as give sense and meaning to the oneness of the Assyrian state as minerals are located in all states of the Federation.
Some Solid Mineral Deposits in Nigeria
1) Talc
Over 40 million tonnes deposits of talc have been identified in Niger, Osun, Kogi, Ogun and Kaduna states. The Raw Materials Research and Development Council (RMRDC)’s 3,000 tonnes per annum catalytic plant is the only talc plant in the country. The talc industry represents one of the most versatile sectors of the industrial minerals of the world. The exploitation of the vast deposits would therefore satisfy local demand and that for export.
2) Gypsum:
Gypsum is an important input for the production of cement. It is also used for the production of Plaster of Paris (P.O.P) and classroom chalks. A strategy for large-scale minor ing of gypsum used in the cement industries is urgently required, to sustain the existing plants and meet the future expansion.
3) iron Ore
There are over 3 billion metric tonnes of iron ore in deposits found in Kogi, Enugu, and the Niger States as well as the Federal Capital Territory. Iron Ore is being mined at Itakpe in Kogi State and is already being beneficiated, up to 67 percent of iron. The Aladja and Ajaokuta Steel complexes are ready for consumers of billets and other iron products for downstream industries.
4)Lead/Zinc
An estimated 10 million tonnes of lead/zinc veins are spread over eight states of Nigeria. Proven reserves in three prospects in the east-central area are 5 million tonnes. Joint venture partners are encouraged to develop and exploit the various lead/zinc deposits all over the country.
5) Gold
There are proven reserves of both alluvial and primary gold in the schist belt of Nigeria located in the southwestern part of the country. The deposits are mainly alluvial and are currently being exploited on a small scale. Private investors are invited to stake concessions on these primary deposits.
6) Bitumen
The occurrence of bitumen deposits in Nigeria is indicated at about 42 billion tonnes; almost twice the amount of existing reserves of crude petroleum. Analytical results suggest that this potential resource can be used directly as an asphalt binder. Most bitumen used for road construction in Nigeria is currently imported.
7) Coal
Nigerian coal is one of the most bituminous in the world owing to southwestern ash content and therefore the most environment-friendly. There are nearly 3billion tonnes of indicated reserves in 17 identified coal fields and over 600 million tonnes of proven reserves.
8) Rock Salt
The national annual demand for table salt, caustic soda, chlorine, sodium bicarbonate, sodium hydrochloric acid, and hydrogen peroxide exceeds one million tonnes. A colossal amount of money is expended annually to import these chemicals by chemical and processing companies including tanneries and those in food and beverages, paper and pulp, bottling, and oil sectors.
9) Gemstones
Gemstone mining has boomed in various parts of Plateau, Kaduna, and Bauchistatese fo,r years. Some of these gemstones include sapphire, ruby, aquamarine, emerald, tourmaline, topaz, garnet, amethyst; zi,rcon, and flourspar which are among the world’s best. Good prospects exist in this area for viable investments.
10) Kaolin
A, n estimate to serve of 3 billion tonnes of good kaolinitic clay has been, identified in many localities in Nigeria. Lift from pages 4 and 5 of Local Sourcing of Raw Materials.
