INVESTIGATION OF ALUMINUM DROSS – GLASS MIXTURES

Aluminium dross treated with hydrometallurgical process mainly consists of spinel, wurtzite and alumina. This composition makes the dross to be a promising secondary raw material for the ceramic industry. Many application fields (refractory, concrete, cement, alumina) are presented in the literature. However, as for the glass industrial application, there are limited research results available. In this study, the effect of aluminum dross and cyclone powder on the properties of melted glasses was investigated. Four drosses and two types of cullet (float and packaging glass) were used. The melting behaviour of the glasses and the mixtures were characterized by heating microscopy. Mineral phases of the raw and the melted materials were identified as well.
