Black smokers active today deposit piles of iron, copper, zinc, lead, silver and gold sulphide minerals over vast areas of the sea floor. Like geothermal hotsprings on land they are modern analogues for ancient mineral deposits that formed in the same manner.

Current models for the origin of banded ironformation (BIF) derived in situ iron ore deposits assume that the typical chert and iron oxide banded BIF is the primary rock from which enriched iron ore deposits arise by the selective leaching of quartz and the residual accumulation of the iron oxides.

Mining Iron Ore in Africa. Because iron ore is the key ingredient of steel, and nearly 95% of the metal used every year around the world is steel – iron is the most frequently used metal in the world. Ironrich rocks are found all over the world but the rocks are only oregrade and suited for commercial production in some countries.

Arguably, the key development came in 1783 4, when Henry Cort introduced the puddling and rolling techniques. These were ways of getting all the impurities out of iron and allowing largescale production, and a vast increase in it. The iron industry began to relocate to coal fields, which usually had iron ore nearby.

Deposits in Cherokee and Henderson counties are mined chiefly as a source of iron for the manufacture of cement. Several deposits of iron ore minerals are present in Central Texas, such as the magnetite deposits at Iron Mountain in Llano County and the hematitic sandstone deposits in Llano, Mason, McCulloch, and San Saba counties.
