Apr 01, 2012· Roy et al. used gold mill tailings to make bricks by mixing them with OPC, black cotton soils or red soils. The OPC-tailings bricks were just cured by immersing them in water but the soil-tailings bricks were sun-dried and then fired at high temperatures (750, 850, and 950 °C).
Japan uses flotation iron ore tailings and coal tailings as the main raw materials to make sewer clay pipes, and the Japanese Institute of Pollution Data has patented the use of them as lightweight porous material. China applies iron ore tailings to non-fired bricks, glass, glass-ceramics, fine concrete aggregates, and road bases.

Sep 10, 2015· Roy et al. [7] used gold mill tailings to make bricks by mixing them with OPC, black cotton soils or red soils. The OPC-tailings bricks were just cured by immersing them in water but the soil-tailings bricks were sun-dried and then fired at high temperatures (750, 850, and 950° C.).
Oct 19, 2015· Bricks made from tailings cost more than conventional bricks because of the higher quantity of cement used, but the manufacturing process consumes less water. Overall, the results indicated that gold mine tailings have a high potential to substitute for the natural materials currently used in brickmaking.

China applies iron ore tailings to non-fired bricks, glass, glass-ceramics, fine concrete aggregates, and road bases.
The current efforts are focused on finding different additives that enable the manufacturing of even stronger bricks in order to meet the existing market demand. The research undertaken by Lianyang Zhang, Ph.D. from Arizona University, is an experimental case about the use of tailings in construction bricks.
brick [5, 6]. It is also noted that there is a shortage of clay in many parts of the world. To protect the clay resource and the environment, some countries such as China have started to limit the use of bricks made from clay [7]. The OPC concrete bricks are produced from OPC and aggregates. It is well known that the production of OPC is

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.
In Arequipa - Peru, tailings produced from the gold cyanidation process are deposited in tailings dumps. This accumulation creates the need for large spaces, high maintenance costs, and a negative impact on the environment. The present study aims to develop a process for reusing gold mine tailings as a raw material for the manufacture of bricks.
