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. Small, low-capacity mines have rapidly disappeared.
Mining and metallurgy The role of filters in mining and . Extraction of iron ore. . differ also in the nature of the extraction process. The energy materials are produced from the ground in a reasonably concentrated state, and subsequent processing involves refining with relatively little waste (except perhaps for coal and oil shales – and, as reserves become exhausted, the processing will.

The top gas utilization (TGU) improves from 47.5 to 49.0 (an increase of 1.5 ) due to better contact of the ferrous burden with the CO-rich gas in the furnace center.
PHASE 1. The initial phase of mining, from discovery until the 1950’s, was for direct shipping ore (also called natural ore). These ores were pockets of high grade iron concentrations that formed within banded iron formations by leaching of silica by surface water or deeply circulating ground water. PHASE 2. Beginning in the late 1950’s a.
