Increasing environmental compatibility of metal production

Abstract

Building materials production generates a large amount of harmful substances poisoning the atmosphere. One of the major sources polluting cities environment is metallurgical industry. Concentration is one of the most important processes where empty components are extracted from the rock. During ore concentration, an increasing number of manmade wastes are generated; they pollute the air and huge area around the factories discharging these wastes. This reduces both space for people to live and place for cities to function and develop. It should be noted that metal production enterprises have accumulated billions of tons of industrial wastes (tailings) that include a large amount of iron-containing materials and rocks; these can be used as building materials, for example, when preparing fine-grained concrete as a mineral powder as well as in construction of roads, houses, in paint production, etc.

Arctic waters: port Sabetta development

“…Thawing permafrost destabilizes infrastructure, increases erosion, and releases stored greenhouse gases, amplifying the region's contribution to global warming. These changes not only impact the physical resilience of port infrastructure but also exacerbate ecological vulnerabilities, such as habitat loss and species displacement [16][17][18][19][20][21][22][23][24][25].…”

Determination of the magnetic separator separation function

“…Polluting impurities are solids, hardness salts, heavy metal ions and organic substances. Untreated waste water that contains suspended impurities and aggregates, are the cause of the violation of the ecological system with all of its negative effects: shoal and dryen rivers, the vegetation dries, fades surrounding life [8,9]. Turnover out a huge area, where merge slimes from the enrichment process of iron ore [10,11].…”

“…To improve the efficiency of dry separation tailings of metallurgical production is possible due to the overlapping processes of magnetic extraction of ferrous particles and air stiring separating the material [9,14].…”
