Separation methods based on gravity or density can be used to improve the quality of ore for DRI. Particles of different densities are separated in a medium of intermediate density, such as a suspension of fine heavy particles in water in a solution of a salt, such as calcium chloride and various bromides or a in a true heavy liquid, such.
Gravity separation and strong magnetic separation are mainly used for the separation of coarse grained (20~2mm) and medium grained weakly magnetic iron ore. Because of these two methods, there have been great advances in technology in recent years. At present, China has begun to use For selecting fine grained weakly magnetic iron ore.
The extraction of iron from its ores is quite a technical process. The iron ore is first roasted in air to produce iron(III) oxide which is mixed with coke and limestone and then further heated to a very high temperature in a blast furnace. These materials are loaded into the blast furnace from the top while a blast of hot air is introduced into it from beneath via small pipes known as tuyeres.

Oct 04, 2018 Magnetic separation is an old technique for the concentration of iron ores and for the removal of tramp iron. Since 1849, a number of patents on magnetic separation have been issued in USA, and texts of some of the patents before 1910 describe a variety of magnetic separators for mineral processing. Magnetic separation methods are used to take.
Mar 19, 2017 Beneficiation of Iron Ore and the treatment of magnetic iron taconites, stage grinding and wet magnetic separation is standard practice.This also applies to iron ores of the non magnetic type which after a reducing roast are amenable to magnetic separation. All such plants are large tonnage operations treating up to 50,000 tons per day and ultimately requiring grinding as fine as minus 500.
Gravity separation method for iron ore , gravity separation is the best proven and accepted technique of concentrating iron ore gravity separation method, gravity separation wikipediaravity separation is an industrial method of separating two components, either a suspension, or dry granular mixture where separating the components.

Magnetic separation. Iron is a metal with magnetic properties. Iron ore can be separated from waste rock by using magnetic separation techniques. Conveyor belts carry the ore past strong electromagnets which remove the magnetic pieces (containing the iron) from the non magnetic waste. How do you think this works Study the following diagram.
