Mining iron ore begins at ground level. Raw iron ore materials will be mined from the mines. Next is the crushing, separating process. The crude iron ore is delivered to large crushers, where chunks as large as five feet are reduced to six inches or less. More than 6,000 tons of iron ore can be crushed in one hour.


At the Itakpe iron ore mine, the ratio of waste to ore is 4:1. The ratio of tailings to concentrate is commonly very high, generally around 200:1 [6]. For instance, it has been reported that in Western Australia, on average, the production of 1 tonne of iron ore results in the generation of 2 tonnes of iron ore tailings [7].

The country's mineral endowment includes gold, tin, iron ore, lead, zinc, barite and bitumen. In the north, security for mining operations is undermined by Islamic insurgency and clashes between farmers and herders over land.


Extraction of Iron. The cast iron is usually extracted from its oxide ore (haematite). This process involves the following steps: 1) Concentration. The ore is crushed in jaw crushers and is broken to small pieces of about 1 inch in size. The crushed ore is concentrated by gravity separation process in which it is washed with water to remove ...


The rate of reduction of both iron ore and quartz varies (Figures 1 to 3). Quartz dissipates easily, breaking down to fines with little applied stress. Though the hardness value of quartz (i.e. 7 on the Mohr's scale) is a bit higher than the iron ore (Hematite (5.5-6.5), Magnetite (5.5-6), it is far more brittle than iron ore (Gribble, 1988).
