Though considered a pollution-intensive industrial activity, iron and steel manufacturing remains pivotally important for the global economy and sustainability [16]. In order to maintain a stable blast furnace operation, artificial lumping of iron ore is a necessary practice via iron ore sintering technology.
The topic of dust pollution caused by mining activities is back on the agenda in Western Australia due to monitoring failures in Port Hedland and excessive levels of particulate discovered in the area close to the Newman Mine – the world's largest open-cut iron ore mine. ... did not report ongoing problems to the regulator regarding a key ...
Pollution Prevention and Control Target Pollution Loads Treatment Technologies Emissions Guidelines Monitoring and Reporting Key Issues Sources ; Industry Description and Practices. Steel is manufactured by the chemical reduction of iron ore, using an integrated steel manufacturing process or a direct reduction process.
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 …
Fig. 2 illustrates the iron ore beneficiation process, particularly magnetic separation, resulting in the generation of inevitable tailings. Due to the characteristics of iron ores and the conditions during beneficiation, it is inevitable that approximately 2.5–3 tons of IOTs are generated for every 1 ton of iron ore concentrate produced [7].In 2019, the global annual …
