Study of the Efficiency of Two Clays Soils for Cyanide Removal in Water: Kinetic and Equilibrium Modelling
Raymond KABORE, Yacouba SANOU, Adama KONATE, Samuel PARE
In Burkina Faso, water resources in mining area are sometime polluted by cyanide. To mitigate this pollution, clays have been collected in Kaya and Koro and used as adsorbents to remove cyanide in waters. Experiments have been carried out using batch adsorption with synthetic cyanide solutions. The influence of operating conditions has been ev(...)

Abstract: The resistance to synthetic pesticides in Anopheles mosquitoes and phytopathogenic fungi constitutes a
major concern. The search for natural pesticides is further encouraged. Essential oils (EOs) of Mentha piperita
and Cymbopogon citratus constitute a potential source of molecules with pesticidal activity but at high doses.

Manufacture of Industrial refractory crucibles based on clays from Burkina Faso
Kassoum Barry, Youssouf Sawadogo , Moustapha Sawadogo, Brahima Sorgho, Mohamed Seynou, Boubié Guel, Philippe Blanchart, Lamine Zerbo
In Burkina Faso, one of the three largest gold producers in West Africa, foundry activity is often paralyzed when basic equipment such as crucibles and cups are not available or should be imported. However, previous studies have shown the availability of kaolinite-rich clay resources that could be used for the local manufacture of silico-alumi(...)

Study of thermal shock and chemical durability of a porcelain formulated from local raw materials from Burkina Faso
Youssouf Sawadogo, Moustapha Sawadogo, Issiaka Sanou, Joël Samba, Mohamed Seynou, Philippe Blanchart, Lamine Zerbo
This work evaluates the resistance to chemical attack and thermal shock of porcelain formulated from local raw materials from Burkina Faso for their validation in real use. A kaolinitic clay, a pegmatite and sand were used for the formulation of porcelain tiles. Some samples were shaped by casting into porous molds and sintered at a temperatur(...)
