NATURAL RESOURCES SUSTAINABILITY IRON ORE

The energy impact index considers the ore grade by applying a function that reflects the relationship between the iron percentage and CO 2 emissions. The energy used to release low-grade iron ore is greater than the demands of a DSO. Nevertheless, at times, DSO does not have a high grade after mineral processing. Figure 1. Iron ore grade and CO

The Contribution of PCSIR towards Exploration of

Mineral processing at PCSIR Most of the ores when mined are low-grade in nature. These ores are not suitable for final applications until and unless the unwanted impurities are removed from them and valuable minerals are concentrated. It is necessary to develop an appropriate beneficiation process for every ore on laboratory scale.
