separation method of iron ore

separation method of iron ore

To separate the ore from the waste rock, first the rocks are crushed. Then the minerals are separated out of the ore. There are a few methods for doing this: Heap Leaching: the addition of chemicals, such as cyanide or acid, to remove ore. This is often done at very high temperatures

Gravity separation and magnetic separation are mainly used to separate coarse-grained and medium-grained weakly magnetic iron ore (20~2 mm). During gravity separation, heavy medium or jigging methods are commonly used for the gravity separation of coarse and very coarse (>20 mm) ores; spiral chutes, shakers and centrifugal concentrators for medium to fine (2~0.2mm) ores, etc. Reselect method

Traditional integrated steelworks use iron ore, coal, limestone, and oxygen or air to produce steel. The first step in this process is the conversion of coal to coke, a porous, strong, carbon-rich material used in blast furnaces to provide most of the reducing power and heat required to reduce iron from iron oxides

Dec 01, 2003 · Abstract. Gold in iron ore samples is separated from iron (major matrix cation), antimony and vanadium using anion exchange resin in (0.2 M) HBr, potassium peroxodisulfate and acetone:water:nitric acid media. The exchangeable anion Cl − of the ion exchanger Dowex 1X 4 is replaced by Br − using (6 M) HBr solution

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 as a thallium malonate/formate solution
