Development Of Geopolymeric Materials From Industrial Solid Wastes

Flotation tailings resulted from the mineral pro-cessing of mixed sulfides ores represent the main source of the generation of acid mine drainage (AMD). These solid wastes remain un-utilized in the disposal areas (tailing dams), while for their stabilization and the immobilization of the contained heavy metals highly costly management techniques are required. In the present paper the geopolymerization of the flotation tailings resulted from copper sulfide ores dressing process is investigated, as an alternative method for their treatment aiming at immobilize the contained heavy metals and utilize the produced materials as raw materials in the construction materials industry.
