STUDYING THE POSSIBILITIES OF USING IRON ORE WASTE İN THE PRODUCTION OF CERAMIC PRODUCTS

Abstract

Decorative ceramic brick for interior decoration is one of the most modern trends in architecture and construction. This type of masonry, facing wall materials, which became popular in the middle of the last century, is becoming more and more widespread over time. In order to expand the disposal of industrial waste, the issues of using iron ore recycling products together with other industrial waste in the technology of wall ceramic materials were considered. The functional purpose of the studied iron-containing waste in ceramic technology is based on the well-known role of iron oxides, which ensure the progress of the sintering process of ceramic materials with the presence of a liquid phase at a significantly lower combustion temperature. 10 mln. in the process of enriching the iron ore extracted from the Dashkasan iron ore deposit located in the territory of the Republic of Azerbaijan. more than a ton of waste was collected. This waste contains up to 12-20% iron, it also contains cobalt, copper and zinc metals. It is clear that producing products from man-made deposits is much cheaper than natural deposits. For this purpose, it is possible to obtain a quality product by using man-made waste using existing technologies and saving natural raw materials. Both blast furnace and agglomeration wastes generated in the mine are considered complex raw materials for obtaining iron, cobalt, copper and zinc from them, although they are useful for high-grade concrete, construction and repair of highways. Therefore, the recycled waste obtained after removing the iron and non-ferrous metals contained in them can be used to buy building bricks, silicate bricks and other ceramic products, but for the final solution of this issue, it is necessary to conduct more precise technological and semi-industrial tests.
