2020年2月8日 The iron ore industries of India are expected to bring new technologies to cater to the need of the tremendous increase in demand for quality ores for steel making. With the high-grade ores depleting very fast, the focus is on the beneficiation of low-grade resources. However, most of these ores do not respond well to the conventional
خبير الاتصالIron ore beneficiation can be brought about through three approaches, namely, selective dissolution, microbially induced flotation, and selective flocculation–dispersion. The bioprocesses are specially suited to treat fines, slimes, and waste tailings. 4. Potential applications include.
