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 …

the benefaction process. The ore grinding must be optimized with respect to the leaching, roast-leaching, or possible benefaction circuits as tabling, flotation, high intensity magnetic separation, heavy media, and others. Liberation of the mineral by the process is governed by the grain size and the mineral complexity of the ore (Ritcey, 1989).

Gravity separation has been applied to process chrome slag by steel researchers in India. Heavy media separation (Choudhury et al., 1996) and crushing and jigging (Khan et al., 2001) are the principal techniques used. The slag is subjected to 2-stage crushing to reduce the size to −10 mm and then screened into −10 +1 mm and −1 mm ...

Therefore, it is ideal to reject these minerals at an early stage in the process. Sensor-based ore sorters can be effective in the rejection of iron -silicate minerals . These sorters are usually installed after the crushing plant, just upstream of the beneficiation plant. Liberation is a critical factor, as the effectiveness of ore sorting is ...

The typical stages of mineral beneficiation are as follows: Communication Communication is made on dry material or slurries to reduce their size. Communication involves either the crushing or grinding of ores. The crushing process is by the run-of-mine, whereas the ground, i.e. the second step after crushing, is on dry material.
