2018 10 23ensp;0183;ensp;The Lower grade sources of iron ore generally require beneficiation, using techniques like crushing, milling, gravity or heavy media separation, screening, and silica froth flotation to improve the concentration of the ore and remove impurities. The results, high quality fine ore powders, are known as fines.. Magnetite. Magnetite is magnetic, and hence easily separated from the gangue minerals

Discover Magnetite Processing. Most traditional iron ore projects mine ore deposits that are enriched naturally and contain high levels of iron known as hematite or direct shipping ore (DSO).DSO passes through a simple crushing, screening and blending process (beneficiation) before it is shipped overseas, mainly for steel production.
Definition The term ore is defined in the current study to describe a concentration of non metallic, e.g., feldspar, or metallic minerals, e.g. spodumene, in pegmatitic rocks irrespective of its structure and position in the deposit which was or is currently mined for a profit.
This is when solid particles stick to one another, and while this is an undesirable feature in many powder and particle processing operations, it is essential for the successful sintering of iron ore fines, coke and fluxes into a suitable blast furnace feed.
