2020-4-29Iron ore is any rock that contains a usable quantity of iron. Common ore minerals include hematite magnetite limonite and siderite and these are frequently found together with assorted silicates. Although iron does not occur in its pure form in nature some kinds of ore contain up to 70 iron atoms. Iron ore consists of oxygen and iron

2019-6-20Modern mining methods allow us to easily reach most of our coal reserves. Due to growth in surface mining and improved mining technology the amount of coal produced by one miner in one hour has more than tripled since 1978. Surface mining is used to produce most of the coal in the U.S. because it is less expensive than underground mining

The blast furnace is filled with iron ore limestone and Coke. Once the impure iron is process it forms a substance known as pig iron. Direct iron deduction uses methane gas instead of Coke to refine iron. The iron is heated hot enough to burn off impurities but not enough to melt the iron. This produces a solid powdery form of iron called

Once the ore has been mined it is usually crushed into smaller pieces that can be processed more easily. The mineral then needs to be removed from the ore. Ancient peoples soon learnt that fire could be used to refine and purify the metals. This technique is known as smelting. This was the earliest method used to extract the mineral from the ore
