Iron processing - Ores Britannica

As-mined iron ore contains lumps of varying size, the biggest being more than 1 metre (40 inches) across and the smallest about 1 millimetre (0.04 inch). The blast furnace, however, requires lumps between 7 and 25 millimetres, so the ore must be crushed to reduce the maximum particle size. Crushed ore is divided into various fractions by passing it over sieves through which undersized material ...

Technological Choices in Iron Ore Mining

Iron ore is available in two basic forms, namely, as boulders on the sur face and hidden in situ which require open cast mining. Primarily there are two different tasks defined in ore mining, namely, excavation and beneficiation or treatment. Extraction depends upon ore type, shape of the ore body, contour, and texture. If ore is available in the form of boulders and pebbles, it is normally ...
