Iron Ore Services. A range of magnetic separation processes from low intensity magnetite ore beneficiation to high intensity recovery of hematite values from waste rock are available. Gravity separation can also be used to recover iron values from low grade ores. Furthermore, a range of thermal tests to characterise upgraded iron ore samples is also...
Finegrained iron ore is processed into coarsegrained clumps for use in the blast furnace. Coal is cleaned of impurities in a coke furnace, yielding an almost pure form of carbon. A mixture of iron ore and coal is then heated in a blast furnace to produce molten iron, or pig iron, from which steel is made.
Sulphur has to be removed first in a separate process. Magnesium powder is blown through the molten iron and the sulphur reacts with it to form magnesium sulphide. This forms a slag on top of the iron and can be removed. Removal of carbon etc. The still impure molten iron is mixed with scrap iron (from recycling) and oxygen is blown on to the mixture. The oxygen reacts with the remaining impurities to .

Abstract: Iron ore and tin mineral are the mainly recovered minerals of the lowgrade ore, which could be effectively separated by a strong magnetic separationgravity concentration process, with ore iron grade of %, tin grade %.
Openpit mining is a type of strip mining in which the ore deposit extends very deep in the ground, necessitating the removal of layer upon layer of overburden and ore. In many cases, logging of trees and clearcutting or burning of vegetation above the ore deposit may precede removal of the overburden.
Gold in iron ore samples is separated from iron (major matrix cation), antimony and vanadium using anion exchange resin in ( 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.
