Mineral Resources in Kogi State

In this article, we will look at the Mineral Resources in Kogi State with their geographical locations and uses with short descriptions about them, so below i will put in a table how many Mineral Resources are in Kogi State With where they can be found.

Kogi State popularly known as the Confluence State is located in north-central geopolitical zone of Nigeria. The State was created on 27th August, 1991 by the then Head of State, General Ibrahim Gbadamosi Babangida from part of Kwara State and Benue State and it has twenty one (21) Local Government Areas.

The State is the only State in Nigeria which shares boundary with ten (10) other States. It is bordered to the north by the Federal Capital Territory and Niger State; to the north-west by Kwara State; to the northeast by Nasarawa State; to the west by Ondo and Ekiti States; and to the east by Benue State. It also shares boundary with Anambra State to the south; Edo State to the south-west and
Enugu State to the south-east.

There are three (3) main ethnic groups and languages in Kogi State: Igala, Ebira, and Okun (a Yoruba group) with other minorities like Bassa (a small fraction of Nupe), Ogori Magongo, Oworo (a Yoruba group), Ogugu (subgroup of the Igala), Gwari, Kakanda, and the Eggan community.

Kogi State is blessed with abundant mineral resources distributed fairly in the two geological segments of the State. According to reports by the Geological Survey of Nigeria Agency (GSNA), the State has over twenty (22) known major mineral deposits distributed in its twenty one (21) Local Government Areas and offers considerable attraction for investors. Kogi State is home to the largest iron and steel industry in Nigeria known as Ajaokuta Steel Company Limited. One of the largest cement factories in Africa, Dangote Cement Factory is built in the State.

Mineral Resources in Kogi State

Geological Survey of Nigeria Agency (GSNA) has played an active role in the exploration for mineral deposits in Nigeria. Kogi State like other States in Nigeria is found to be endowed with mineral resources. The mineral resources so far reported in the State by the Geological Survey of Nigeria Agency are discussed below:

Beryl

Beryl is a hard, crystalline mineral, composed of beryllium aluminum silicate that occurs in white, yellow, pink, green, or blue forms. In other words, it is a hexagonal mineral, Be3Al2Si6O18, from which beryllium is extracted; its principal occurrence is in granite pegmatites. Beryl is a major gemstone; when green, it is emerald, when blue or bluishgreen, aquamarine, and when pink, morganite. Beryl is found at

  • Ikoyi in Ijumu Local Government Area
  • Aku in Adavi Local Government Area

Both areas are underlain by migmatites. The mineral is used as gemstone.

Cassiterite

Cassiterite is a dark-coloured mineral consisting of tin oxide, SnO2, the major ore of tin. Otherwise known as tin ore cassiterite belongs to the class of metalliferous minerals. It is associated with hydrothermal veins and pegmatites. Some deposits also occur in placers as well as in granite. The area in the State where the mineral is found is Okoloke in Yagba West LGA.

Tin is a widely sought metal and is used in hundreds of industrial processes throughout the world. In the form of tinplate, it is used as a protective coating for copper vessels, various metals used in the manufacture of tin cans, and similar particles.

Tin is important in the production of the common alloys bronze (tin and copper), solder (tin and lead), and type metal (tin, lead, and antimony). It is also used as an alloy with titanium in the aerospace industry and as an ingredient in some insecticides. Stannic sulphide, known also as mosaic gold, is used in powdered form for bronzing articles made of plaster of paris or wood. Its compounds are used in dyeing and fire-proofing.

Clay

Clay is naturally occurring material composed primarily of fine-grained minerals, which show plasticity through a variable range of water content, and which can be hardened when dried and/or fired.

Clay is found all over the 21 Local Government Areas of the State. The uses of clay and clay products are too numerous to list completely. In domestic life clay is used in pottery, earthenware, china, cooking ware, vases, ornaments, plumbing fixtures, porcelain stoves, tiles, fire kindlers, oilcloths, linoleum, wall-paper, scouring soaps, and polishing bricks.

It even finds a place as an adulterant in foods and medicine. In buildings it is used for building bricks, vitrified and enameled bricks, building and conduit tiles, tiles for floors, walls, and drains, copings, flues, chimneys pots, sewer pipes, and foundation blocks. In electrical industry it is used for conduits, cleats, sockets, insulators, and switches. In refractory ware it is used for fire brick, furnace linings, chemical stoneware, crucibles, retorts, glass-melting equipment, and saggar.

Other important uses are for furling cloth, foundry sands, terra cotta, emery wheels, rubber crucibles, water conduits, paving bricks, septic tanks, railroad ballast, Portland cement, filtering oils, paper making, and innumerable minor purposes.

Coal

Mineable coal deposits in the State are found at

  • Odokpono, Okobo and Odagbo (Okaba) in Ankpa LGA
  • Ogboyaga in Dekina LGA.

The coal deposits in Kogi State are of medium quality, non-coking and sub-bituminous. These put together suggest that they do not possess some cooking qualities suitable for coke making blends.

However, the coals are suitable for electric power generation and as domestic fuel. They are also rich in resinous and waxy materials and are therefore suitable raw material for the chemical industry and also for use in the manufacture of plastics, when fractionally distilled. The coals are also good producer of gas fuel, and are suitable for complete gasification using the oxygen enriched steam blast process. They can also be processed to produce automotive fuel.

Columbite

Columbite is an iron black, often iridescent, orthorhombic mineral oxide of niobium, tantalum, iron, and
manganese (Fe,Mn)(Nb,Ta)2O6, with varying proportions of niobium and tantalum. When the proportion of tantalum exceeds that of niobium, it is called tantalite. Columbite is the principal commercial source of tantalum and niobium. In most cases, columbite in the State occurs in association with tantalite.

Most of the columbite in the State is concentrated in alluvial deposits. Few deposits occur with tinstone in granite and pegmatite.
Columbite is found at

  • Isanlu–Esa, Okoloke, Odo Eri and
  • Ejiba in Yagba West LGA;
