Provides basic information about the mining cycle, from exploration for economic mineral deposits to mine closure. The booklet discusses the environmental aspects of metal mining and illustrates the ways science and technology …

Mining activities have resulted in the existence of dumps, which generally present a perpetual danger of moving and transforming toxic elements. The experimental study was carried out in Nizna Slana (Slovakia) where the main source of emission was the iron-ore mining–processing factory focused on siderite mining. Siderit from Nizna Slana is highly …

To quantitatively evaluate the carbon emission effects of various underground mining schemes in metal mines, a carbon emission calculation model specifically for underground metal mines was established. The carbon emissions stemming from the mine's production process were categorized into three components: carbon emissions from the production of …

The dust emission from the mining area is the primary source of air pollution for the surrounding environment. This paper deals with the study of baseline air quality assessment and air pollution ...

Increased mining activity of iron ore has led to the generation of voluminous wastes of various nature, especially during the different stages of its extraction and production. The improper disposal of such waste causes negative impact on the environment. One such waste which is generated during the beneficiation process of iron ore is waste iron ore tailings, which …

The Supreme Court Central Empowered Committee has assessed that even at conservative estimates, at the present rate reserves in the State will be exhausted in about 20 years. Iron ore mining in Bellary took off in 1999, paved by the 1993 National Mineral Policy that began encouraging private players to participate in iron ore mining [10,11].

Dust emission is one of the critical problems of the mining industry. Dust emission can cause respiratory diseases among workers and adjacent residents of the factory and environmental pollution in the region. This study aims to reduce dust emissions of an iron ore concentrate plant in Iran. Applying dust control methods can affect the production process. …

The mining of iron ore is highly energy intensive and causes air pollution in the form of nitrous oxide, carbon dioxide, carbon monoxide, and sulfur dioxide from diesel generators, trucks and other equipment. The mining of iron ore also causes water pollution of heavy metals and acid that drains from the mines.

Heavy machinery used in the mining process and the constant movement of trucks carrying iron ore contribute to air pollution by releasing diesel exhaust and fine particles into the atmosphere. The lack of greenery in the mining zones exacerbates the problem, as there are fewer natural barriers to absorb dust or filter the air.

The exploitation of iron ore could cause heavy metals pollution in the soils, which threatens the ecosystem and human health. In this study, soil, stream sediment, tailings, rock, and atmospheric deposition samples were collected from an iron mine in Baotou City. The concentrations of As, Cd, Cr, Cu, Hg, Ni, Pb, Zn, Al2O3, CaO, K2O, MgO, Na2O, SiO2, and …

When metal-bearing ore is exposed during iron ore mining instead of the ore body being naturally exposed through erosion, and when mined ore is exposed to the surface during the beneficiation process, there is a greater chance of …

Zinc extraction residue, a solid waste generated from the treatment of zinc-containing dust in rotary kilns, is commonly stockpiled in steel companies for extended periods. It poses significant disposal challenges and environmental pollution risks. So far, research on the treatment of zinc extraction residues has been slow, inadequate, and sporadic. For this gap, a …
