Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel—98% of the mined iron ore is used to make steel Indeed, it has been argued that iron ore is "more integral to the global economy than any other commodity, except perhaps oil "
Magnetic material remains as a concentrate and is transferred to the primary grinding plant The primary grinding plant of four ball mills grinds the ore in slurry into fine particle sizes of
Iron ore concentrates are characterised by low sulphur and phosphorus content Iron ore concentrate recovery is based on magnetic beneficiating methods The ultra pure iron concentrate is widely used in steelmaking, metallurgy, chemistry, powder metallurgy, magnetic materials, food conservation, environmental protection, medical treatment, etc
Process Flowsheets High grade concentrates and high recovery of iron ore can be achieved using effective feed preparation systems (typically controlled crushing, screening, milling, classification and slimes removal) in combination with cost effective, efficient metallurgical separation
Types of Iron Ore: Hematite vs Magnetite , this type of iron ore ore must be concentrated before it can be used to produce steel Magnetite ore’s magnetic properties are helpful during this .
Oct 04, 2018· Magnetic separator separates the iron ore feed material into two or more components If the purpose is to produce a magnetic concentrated iron ore then the other component which is non-magnetic is the tailings In some cases there can also be a possibility of separating the less magnetic third component which is called middlings
We have set up a team with hundreds of technical engineers to resolve a series of problems during project consultation, on-site surveys, sample analysis, program design, installation, commissioning and maintenance guidance.
