Over 13.9 million tons of limestone was recorded to have been mined in Nigeria in 2017. Ogun state produced about 7.4 million tons of this resource. Thus, accounting for more than half of the total limestone produced in Nigeria.
Ogun state is followed by Kogi state which produced approximately 3.6 million tons, Gombe produced 1.1 million tons, Cross River produced 693,000 tons, Benue produced 421,000 tons, Sokoto produced 394,000 tons, Edo produced 386,000 tons, Ebonyi 48,000 tons and Abuja produced over 2900 tons.
In West Africa, Nigeria is considered to have the richest deposits of limestone. The largest and purest form of these deposits is predominantly found in the middle belt and southwest belt; where the projected quantity is estimated to be at about 31 million metric tonnes. However, not all locations where this mineral is identified can be exploited for economic purposes.
