The possibility of using iron-ore enrichment tailings in the production of ceramic articles is investigated. The compositions and properties of ceramic bodies and the process parameters for manufacturing articles are presented. To increase product quality nepheline concentrate is used as an alkali-containing additive.

The water absorption of the ceramic articles obtained is less than 18%. This corresponds to the requirements of the standard RST RSFSR 604.91 ‘Ceramic Articles from National Art and Pottery Industries’.
