Techniques of surface mining include: open-pit mining, which is the recovery of materials from an open pit in the ground, quarrying or gathering building materials from an open-pit mine; strip mining, which consists of stripping surface layers off to reveal ore/seams underneath; and mountaintop removal, commonly associated with coal mining ...Web
microbial organisms necessary to sustain plants. Mining operations often require that topsoil be stored in stockpiles for long periods of time, often several years. In civil engineering activities, such as road construction, the topsoil is scraped off and stockpiled in large, deep piles due to the limited space that construction staging allows.Web
Materials value chains—including metals and mining, building materials, plastics, and packaging—account for around 20 percent of global greenhouse-gas (GHG) emissions. Some of these value chains …Web
In this paper, we quantify to what extent secondary materials generated through urban mining could replace the primary material demand in the Dutch construction sector. We also explore the potential …Web

These fine-sized mine tailings (<300 μm) can be incorporated into building materials. Cement mortar specimens were fabricated with additions of 0% to 20% of molybdenum mine tailings.Web
Construction and demolition waste and mining waste are currently the biggest waste streams in the EU27 and can lead to environmental, health, and social hazards. The purpose of this study is to evaluate the sustainable use of (clean) sulphidic mining waste materials in facing bricks. After materials' characterisation, a company …Web
Mineral waste can be defined as a material leftover from exploration, mining and quarrying operation that cannot find a productive use. It is the high-volume material that originates from the excavation and physical and chemical processing of a wide range of metalliferous and non-metalliferous minerals by opencast and deep shaft methods [].The …Web
Finally, the use of mining waste in building materials is a resource development strategy for resource reuse, and the paper notes that the use of mine waste in the preparation of building concrete materials …Web
