research on efficiency of hematite iron ore

Hematite is virtually free of contaminants, and is easily mined from a nearly inexhaustible source. Additionally, hematite has three main advantages over barite: (1)higher specific gravity;(2)better particle distribution;and (3) alow particle attrition rate.

Abstract: To enhance effective use of resources, we use magnetic separation method on the experiment study of a refractory oolitic hematite ore. Research showed that: the grade of raw ore (TFe) was 47.44%, and magnetic iron grade (MFe) was 28.59%. Through magnetic separation experiment, three-step magnetic separation process was chosen.

Ironis produced fromiron ore.Ores carrying higher quantityof hematiteor magnetite are called naturaloreand can be directly fed into blast furnace for the extraction ofiron.Iniron oremining process, rocks carrying high quantity oforeare identified, followed by drilling blast holes in the rocks.

Jan 31, 2018· If a mineral deposit is composed of a metal that can be extracted using existing technological methods, then it is called anore.
