As you know, the problem of environmental safety is important in the process of mining and processing of ore and non-metallic minerals. In the process of primary processing of ore minerals, the so-called enrichment tailings or production wastes are formed. The resulting waste accumulates in huge quantities, contributing to changes in the landscape and worsening the hydrogeological and sanitary conditions of the environment. In addition, rainfall and meltwater contribute to the constant leaching of heavy metals from waste dumps, which eventually leads to the pollution of groundwater, rivers and lakes. Therefore, the important ecological task of rational disposal of mining tailings is very relevant around the world. Research aimed at developing and obtaining new materials on the basis of this waste is of the greatest interest. One of such directions is the utilization (immobilization) of mining tailings when obtaining of geopolymer materials, which eliminates the leaching of heavy metals from the volume of the obtained material. Over the past 60 years, millions of tons of enrichment tailings have accumulated at the Dashkesan iron ore deposit, which are waiting to be disposed of. For this reason, the tailings of Dashkesan iron ore enrichment were used as a mineral filler for producing geopolymer material. Mineralogical and chemical compositions of enrichment tailings were studied using X-ray phase and X-ray fluorescence methods. Water absorption of the obtained specimens of geopolymer material was researched in accordance with the known methodology. It was revealed that with the increase of mineral filler content from 60 to 90%wt. the value of water absorption of geopolymer material specimens in the first five minutes of exposure increased from 1 to 10,2%, respectively. With the increase of mineral filler content from 60 to 90%wt. the maximum value of water absorption increases from 2,6 to 10,2%, respectively.
