The mineral industry, which is limited to the production of cement, clay, gold, sand, and gravel, does not play a significant role in the Benin's economy.. Cement was produced by Ciments du Benin S.A., Société des Ciments d’Onigbolo, and Société des Ciments du Benin. These companies had a combined cement production capacity of 1.43 million metric tons per year (Mt/yr).
