Dust emission reduction in iron ore concentrate production

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 Canadian mine production of iron ore in concentrate and pellets was 57.5 million tonnes in 2021, a 2% decrease compared to 2020. Global production of iron ore is estimated to have been 2,537 million tonnes in 2021, slightly higher than the 2,472 million tonnes produced in 2020.

Comminution and classification technologies of iron ore

This concept has been adopted for the FMG Iron Bridge large (16 Mtpa concentrate production) magnetite mine development in Australia (private communications). 8.4. Future trends in iron ore comminution and classification. The in situ grade of magnetite ores is much lower (∼20–50% Fe) compared with hematite/goethite ores.The scarcity of iron ore concentrate resources is a real fact, and a search for alternative resources seems to be unavoidable [1, 2].For many years, magnetite iron ore mines, containing high-sulfur content (up to 2.0%), were not very welcomed in steel industry; however, they are nowadays increasingly receiving attention as potential sources and The role of thermal improvements in indurating machines for
