Also known as red hematite ore of its chemical formula is Fe2O3, which is a weakly magnetic iron minerals, magnetite 1 than good, one of the main raw material is iron. The main 1 technology have re-election, and strong magnetic separation or flotation process and use a variety of mineral, and there have been post-low intensity magnetic separation magnetic roasting process.
In recent years, the mineral hematite has achieved rapid development, the main mineral processing technology are: electromagnetic pulsating high gradient magnetic separator is represented by strong magnetic 1process and represented by series of anti-flotation 1. Especially the use of magnetic – flotation process to make some of mine co-hematite sorting reached grade of iron concentrate and iron ore recovery satisfaction index.
