4.1 Process Overview 4.1.1 Iron Ore Mining There are two basic methods of mining iron ore. These are: • Surface mining or open-pit mining • Underground or shaft mining To be competitive, iron mining must be done on a very large scale. Surface mining is the preferred choice, although there are exceptions.
Iron ore was won by drilling and blasting . As mining technology generally developed, so did drilling techniques and the explosives used. Smith (1990) reported that the …
However, in order to provide an historical context of the early smaller scale of iron ore mining, the chapter begins by examining two examples of historic underground mining in the United...
Lower-grade sources of iron ore generally require beneficiation, using techniques like crushing, milling, gravity or heavy media separation, screening, and silica froth flotation to improve the concentration of the ore and …

During pelletizing, ore powder is rolled into iron ore green pellets in rotating drums together with water, binding agents and additives. Globules with grain sizes of approx. 15 mm are produced, which are then baked into porous pellets. Pellets are mainly produced by special ore suppliers and then delivered to the ironworks.
However, in order to provide an historical context of the early smaller scale of iron ore mining, the chapter begins by examining two examples of historic underground mining in …

Generally, the extraction of metals and their isolation are based on three major procedures. The steps are: 1. Concentration of Ore 2. Extraction of metal from concentrated ore and 3. Purification of the metal In the following article extraction of iron from its ore in the blast furnace is described in light of these three quintessential steps.
Iron metal is usually extracted from a hematite ore, which contains an iron (III) oxide ( F e O 2 3 ) compound. The ore must be treated before it can be placed in a blast furnace, because blast furnaces are usually optimized to burn small pieces of ore that are compacted together.
