Clay materials of the quarry of Bingerville district of Abidjan have been characterized by chemical analysis, X-rays diffraction, infrared spectroscopy and thermal analysis. These materials contain kaolinite 41% - 84%, illite 4% - 10%, quartz 14% - 27%, goethite 2% - 5% and small amount of rutile 1% that are not toxic minerals. They also contain some heavy metals which are beneficial to human biological activity cobalt, copper, molybdenum, zinc in tiny quantities. Some other heavy metals lead, cadmium which are considered as poisonous for human are present in very low content. The samples characterized by relatively fine grains are moderately crystallized.
