As one of leaders of best method for processing microfines of iron ore industry, SBM always seeks innovation & excellence.
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. Since mining began at the site over 100 years ago, Luossavaara-Kiirunavaara AB (LKAB) has produced over 950Mt of ore, yet only one-third of the original ore body has been extracted.

Ores. Niobium occurs mostly as an oxide and has a strong geochemical coherence with tantalum. Major minerals of niobium are pyrochlore [(Na, Ca) 2 Nb 2 O 6 F] and columbite [(Fe, Mn)(Nb, Ta) 2 O 6], consisting of niobate, tantalate, iron, and manganese.Pyrochlore occurs usually in carbonatites and in pegmatite derived from alkalic rocks, commonly in association with zirconium, titanium ...

The per cent of iron in the ore as mined must be not less than 50%, if it is to be used without being first improved (beneficiated) by cobbing, washing, calcining, or magnetic concentration. Leaner ore is found in very large quantities; and in a favorable situation, it may be workable by some concentrating process.

MINING AND PROCESSING: Iron ore mining can be broadly divided into two categories namely 1) manual mining which is employed in small mines and 2) mechanized mining is suitable for large iron ore mines. Manual mining method is normally limited to float ores and small mines. Mining of reef ore is also being done manually on a small scale.

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.
