Methods for utilizing copper mine tailings for production of eco-friendly bricks based on the geopolymerization technology and bricks so produced (Fig. 6). The procedure for producing the bricks includes mixing the tailings with an alkaline solution, forming the brick by compressing the mixture within a mold under a specified pressure, and curing the brick at a slightly elevated temperature.
