Results and discussion. The composition of iron concentrate obtained: % Fe and % phosphorus with an iron recovery of %, and a rate of dephosphorization of %. Figure 2 shows a flowsheet for concentration by reductive sintering and removal of phosphorus.

The current resource life for iron ore of 70 years is skewed by the long life of magnetites of about 900 years. Excluding magnetites the life of Australia's iron ore resources are about 50 years. However, the resource life of Premium Brockman ore is 25 years.

Note: not every material in the above list is available in the ASTAR and PSTAR databases.

Iron is a versatile element used all around us every day. This is a list of iron alloys. Included are various types of iron and steel.

The materials are then fed through a kiln at 2,600º F to produce grayishblack pellets known as clinker. The alumina and iron act as fluxing agents which lower the melting point of silica from 3,000 to 2600º F. After this stage, the clinker is cooled, pulverized and gypsum added to regulate setting time.

Iron ore is used in production of pig iron which is further used in production of steel other uses of iron ore are like industrial finishes, polishing compounds and sponge iron industries. Iron ore belongs to Precambrian stage and its deposit is present in massive, laminated, friable and also in powdery form.
