In which of these groups of areas is limestone actively quarried for the manufacture cement in Nigeria?
Answer Details
The group of areas in Nigeria where limestone is actively quarried for the manufacture of cement is Ewekoro, Nkalagu, and Ukpilla. This is because these areas have large deposits of high-quality limestone, which is a major raw material used in the production of cement. The limestone deposits in these areas are geologically young and have high calcium carbonate content, which makes them suitable for cement production.
