The mining industry is an important industry in South Africa. It involves a number of industries working together. Exploration is followed by excavation, which is followed by crushing and milling to reduce the size of the rocks. This is followed by extraction (removing the valuable minerals from the ore) and finally refining.
The direct shipping ore (DSO) mined in phase one of the mining project is shipped in its raw form at an average of 60% FE to buyers around the world. The Liberia mining project is also unique to ArcelorMittal''s mining portfolio in that this was the first greenfield mine the company operated.
· High-grade hematite ore is referred to as direct shipping ore (DSO) as, once mined, the ore goes through a simple crushing and screening process before being exported for steel-making. Australia''s hematite DSO from the Hamersley province averages from 56% to 62% Fe.
Large tabular-shaped ore bodies or ore bodies lying more than 1,000 feet (300 m) below the surface are generally mined underground as well. The rock is drilled and blasted, then moved to the surface by truck, belt conveyor, or elevator. Once at the surface, the material is sent to a mill to separate the ore from the waste rock.
2019-8-21 · Iron ore is an important raw material in steel production enterprises. After iron ore crusher''s crushing, grinding, magnetic separation, flotation, re-election and other procedures, iron will be gradually separated from natural minerals (iron ore). Theoretically, mineral that contains iron element or iron compound is called iron ore.
With an ore body 4km-long, 80m-thick and reaching a depth of 2km, LKAB''s Kiruna is the world''s largest, most modern underground iron ore mine located in northern Sweden. Since mining began at the iron ore operation more than 100 years ago, Luossavaara-Kiirunavaara AB (LKAB) produced over 950Mt of ore, yet only one-third of the original ore ...

2015-1-1 · Iron ore crushing and screening. Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel. About 98% of the mined iron ore is used to make steel either by the blast furnace—basic oxygen furnace (BF-BOF) route—or through the electric arc furnace (EAF) route.
Primary crushing brings run-of-mine ore down to a maximum size of the order 4″ to 6″ in average diameter; secondary crushing receives feed at −6″ and reduces it to below "Dry" crushing includes work on ore as mined, which may be somewhat moist when delivered. It is succeeded by comminution in water, arbitrarily called "grinding".
