Geology, Prospecting and Exploration for Iron Ore Deposits

2015-4-9  Iron ore deposits are distributed in different regions of the world under varied geological conditions and in different geological formations. The largest ore concentration is found in banded sedimentary iron formations of Precambrian age. These formations constitute the bulk of iron ore resources of the world.get price

5 Ore deposits formed in sedimentary environments

Ore deposits form in sedimentary environments as a result of one of two generalised geological processes: either as a result of mineral precipitation from solution in surface waters, most commonly from sea water or lake waters; or as a result of physical accumulation of ore minerals during processes of sediment entrainment, transport and deposition.get price

Geological ore deposits The Australian Museum

Geological ore deposits are of many different types and occur in all geological environments. The iron and manganese ores occur as distinct sedimentary layers alternating with iron and manganese-poor sedimentary layers the whole mass is sometimes mined. Iron ores of this type are commonly termed the banded iron formation or simplyget price

Iron and Manganese Ore Deposits: Mineralogy,

2020-8-18  The majority of ore deposits of both iron and manganese are of sedimentary origin. At present, high-grade iron ore deposits formed by hydrothermal and supergene enrichment of Proterozoic banded iron formations constitute the most important source for iron ores, with only some magmatic and skarn-type iron ore deposits being mined.get price

Types and general characteristics of the BIF-related iron

2014-3-1  The ores are mainly hematite, with TFe content more than 50%. In China, the BIF-related iron deposits are the most important type of iron deposits, accounting for approximately 64% of the total identified resources.
