Prospects for the Development of Building Ceramics, Based on Stale Slags from the Non-Ferrous Metallurgy of Orenburg

摘要

The article deals with the problems of using wastes formed after extraction of copper, nickel, gold, etc. from slags. A review of existing developments in the field of using technogenic products for the production of ceramic building materials with desired properties was carried out. The results of the study of the prospects of using stale slags from non-ferrous metallurgy on the example of the slags from the Mednogorsk Copper-Sulfur Plant of the Orenburg region in combination with fusible clay from the Alimsaysky deposit for the production of ceramic brick are presented. The data of studying the technological properties of raw materials, the development of compositions are given. The effect of the material composition of the clay/slag mixture on the strength, shrinkage, water absorption and density of experimental samples - bricks after calcination in the range of 900- 1200°C is determined.
