Iron ore is obtained in the conventional method of open cast or underground mining and conveying the ore to the surface preparation are where it is crushed, washed, and transported to the smelter. Here the ore is put into a blast furnace along with limestone and coke and subjected to hot air blasting and heat which converts the ore to molten iron.
Iron ore is obtained in the conventional method of open cast or underground mining and conveying the ore to Underground Mine Mapping Mining Methods Minnesota DNR Underground mining of natural iron ore deposits occurred on the Mesabi Range in northeastern Minnesota from 1892 to 1961.
Mining Iron Ore Mining iron ore begins at ground level. Taconite is identified by diamond drilling core samples on a grid hundreds of feet into the earth. Taconite rock comprises about 28 percent iron; the rest is sand or silica. These samples are analyzed and categorized so that mining engineers can accurately develop a mine plan.
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.
