waste from iron ore crushing

Evaluation of the performance of iron ore waste as

After extraction, the iron ore passes through a refining process that consists of crushing, screening, and flotation. The iron ore residue comes from this process and it is disposed of in piles and dams and treated as an environmental liability To investigate the various types of waste generated by iron mining, a survey is carried out by visiting iron ore mines in India (Odisha) and interacting with A study on waste management in iron mining ScienceDirect
