Adhikari, and R. N. Gupta. 2007. "Use of gold mill tailings in making bricks: A feasibility study." Waste Manage. Res. 25 (5): 475–482. …
The bricks were termed as cement-tailings bricks or soil-tailings bricks, depending on the additives used. The cement-tailings bricks were cured for different periods and their corresponding compressive strengths were determined. The bricks with 20% of cement and 14 days of curing were found to be suitable.
