“…In addition, and more directly related to the present study, numerous works focus on minimizing the environmental impact of the stone industry, and particularly marble, both in its extraction phase and processing (Careddu and Siotto, 2011;Furcas and Balletto, 2014). As highlighted by Taha and Benzaazoua (2020), many different types of waste are produced during the life cycle of a quarry (Figure 1), and the decision of how to manage them depends on numerous factors. Many solutions tend to be specific to each location and are therefore difficult to apply in other cases.…”

“…Mining waste is a usable feedstock that can be utilized as a partial replacement for cementitious material in the manufacture of cement-based materials [10]. This study attempts to use mining waste in brick making, with the goal of determining its ability to capture CO2 during the brick manufacture.…”

Production of waste rocks and overburden from ore mining in open-pit mines can cause undesirable environmental impacts. Thus, this study aims to tackle the issue of waste production from mining areas by utilizing mining waste to sequester CO2 and to evaluate its potential for carbon capture in cementitious material. This study attempts to evaluate the effect of mine waste ratio and carbonation curing time on physico-mechanical behavior of bricks. The bricks were fabricated using different ratios of mine waste, i.e. 20 – 40 % in the mix design. Carbonation curing between 1 – 3 hours was applied during the brick fabrication to estimate CO2 capture of the brick product. The brick performances were evaluated based on the compressive strength, water absorption and carbon capture capacity. It was found that curing time at 28 days provided the greatest compressive strength of the brick and greater performance was observed at 40 % replacement with the mine waste. Carbonation curing improved the brick performance with higher compressive strength and lower water absorption at longer exposure time of 3-hour carbonation. The resulting CO2 uptake was found to increase with the increase of carbonation time and at higher ratio of mine waste replacement. The CO2 capture capacity was between 0.45 – 0.58 % for bricks containing 20 – 40 % of mine waste, which corresponds to 9.4 – 16.3 g CO2/brick. Therefore, it has been shown that the use of mining waste as partial replacement for cementitious material was capable in improving the brick performance with incorporation of carbonation curing process.

“…This has become a global concern as reflected in the intense research interest: between 1988 and 2017, more than 3500 peer-reviewed articles were published that focused on mine waste management. Most were authored by researchers from the USA, Canada, Spain, Australia, and China [15][16][17]. Apart from challenges related to storing mine tailings, soil contamination, and ground and surface water contamination, catastrophic storage facility failures have caused human fatalities [18][19][20][21].…”

The Potential Re-Use of Saudi Mine Tailings in Mine Backfill: A Path towards Sustainable Mining in Saudi Arabia

et al. 2021

The Kingdom of Saudi Arabia covers an area of approximately 2 million km2 and is rich in natural resources that are necessary for industrial development. The estimated mineral wealth beneath the Kingdom’s soil is approximately USD 1.33 trillion, as reported by the Ministry of Industry and Mineral Resources. The Kingdom’s vision for 2030 is to develop the mining sector to become the third pillar of the domestic economy. Therefore, exploration and mining activities are expected to accelerate over the next decade, which will lead to increased waste production. New executive regulations issued in January 2021 contain several sustainable elements related to the environment, social responsibility, and occupational health and safety. Therefore, this study aims to promote an example of sustainable mining activities in the Kingdom that could be adapted to meet the regulatory requirements. Cemented paste backfill samples of varying composition were made with waste materials from a Saudi copper mine for re-injection into underground mining cavities to minimize waste exposure to the environment. The samples were tested for unconfined compressive strength (UCS) after 7, 14, 28, 56, and 90 days of curing. Results from a statistically designed experiment technique show that the samples developed sufficient strength to be used in mine backfilling applications. Strong negative relationships were detected between the UCS and the water-to-binder ratio. There is strong potential for mine backfill technology to be applied to a wide range of Saudi Arabian mines to enhance the sustainability of the mining sector.
