Iron ore beneficiation: an overview
The high-grade iron ore is defined in terms of iron content. In general, cut-off iron content of ROM for such type of ore is kept at approximately 55%, which is obtained by selective mining. The ROM ore is subjected to dry/wet processing through multistage crushing and screening for production of lumps (−40+10 mm) and fines (−10 mm). In the ...
