2023年1月6日 The mining industry manages large volumes of tailings, sludge, and residues that represent a huge environmental issue. This fact has prompted research into valorization of these wastes as alternative aggregates for concrete production, embankments, pavement material, etc. The use of mining wastes as a resource for
Earth’s crust contains many minerals and other materials that are useful to people. To get these valuable natural resources, people must dig into the ground. The holes that they dig are called mines. Some mines are narrow shafts, or tunnels, that go very deep underground. Other mines are large open pits, like canyons. The people who work in
2022年7月21日 More than 80% of mining areas worldwide target materials critical to renewable energy production. 2 Processing ore, transporting it in slurry pipelines, and suppressing mine dust require water, often from regions where water is already scarce. Chile’s Atacama desert, “where I do my work, is the driest desert on Earth,” Odell says.
2016年1月1日 The cost of mineral additives is ∼ 9.5% of the total costs on raw materials and 2.4% of the direct expenses. The production cost of 1 ton of cement with mineral additives was 1757.09 rubles for a selling price of 3964.36 rubles. The factory price of this cement was 3680-4200 rubles, which provides a positive commercial result.
2023年3月19日 Sustainable building materials can be defi ned as materials with overall superior performance in This is the amount of energy consumed to mine, manufacture and transport a particular product. The embodied energy of glass, steel, concrete blocks, bricks etc., or an entire house are measurable. Clay provides the glue which holds the
The use of materials from waste in buildings compensates for the lack of natural resources, solves the problem of waste management and provides an alternative technique for protection of the environment. There are a large number of industrial wastes that are used for full or partial replacement of raw materials in some construction materials.

2021年10月18日 Regulating these activities mainly depends on national frameworks and policies, but implementing good practices remains problematic. To truly shift to “sustainable mining,” governments and companies must recognize the social impacts of mining, and enact laws and regulations that require community consultation throughout the life of a
