8.1. Introduction. Hematite and magnetite iron ores are the most prominent raw materials for iron and steel production. Most of the high-grade hematite iron ores are typically subjected to simple dry processes of crushing and classification to meet the size specifications required for direct shipping ore (DSO).
Dry ore can be moved through chutes, provided they are of sufficient slope to allow easy sliding, and sharp turns are avoided. ... "Beneficiation" of iron ore includes concentration, generally by physical removal of unwanted gangue; also, considered beneficiation is the regulation of product size, or other steps such as agglomeration to ...
The study of beneficiation indicators of the magnetic separator was carried out using iron ore of the Bapy deposit, which is mono-mineral magnetite. For the study, mixtures of the minus 0.1 mm class were selected with the iron content α = 50% and α = 40%.
In mining and minerals industries, whenever water supplies are restricted and also where wet processing leads to problems in handling and dewatering of the products and tailings, dry beneficiation is preferred.
