Investigation of the possibility of production of ceramic tile from tailings of the copper concentration plant

Author(s): M.Mehrabian, A.Sarrafi

Tailings of the copper concentration plants, which mainly consist of fin e aluminusilicate components, have many applications in silicate industry. Their application in the field of ceramic industry is the subject of the present study. Regarding the mentioned target, single soil bodies were created using the waste. The construction was done according to the certain standard procedures. Next, the constructed bodies were compared with the ones made by the main soils of the ceramic industry. Eventually, some ceramic bodies were produced by the combination of the waste and also the main soils of the ceramic industry. Determinations of the chemical and mineralogical compositions were carried out by X-ray fluorescence spectrometry (XRF), X-ray diffraction analysis (XRD) and Scanning electronmicroscopy (SEM). Thermal analysiswas done by Thermo gravimetry (TG) and Differential scanning calorimetry (DSC). Water absorption, bend strength and linear thermal expansionweremeasured according to the ISO10545-3, 10545- 4 and 104545-8, respectively. The results show that the used waste is a proper rawmaterial for the ceramic industry.
