Iron, titanium and vanadium ores

General information and occurrence

Resources of the iron ores were crossed out from the registry of Polish mineral raw material deposits by the decision of the Minister of Environmental Protection, Natural Resources and Forestry already in 1994 as not meeting the criteria for economic ores.

The igneous deposits of the Fe-Ti-V formation – the vanadium-bearing magnetite-ilmenite ores occur in anorthosite complexes of the Proterozoic Suwałki mafic massif (north-eastern Poland - map). The deposits became known thanks to an intense drilling exploration and an appraisal drilling program launched in the 1970s. These deposits were documented at the depth from 850 m to 2,300 m. In order to classify the resources, in 1996 the new balancing criteria were elaborated and accepted. On the basis of these parameters the resources of the Krzemianka and Udryń deposits were at that time classified as anticipated sub-economic on the account of low contents of metals, especially vanadium (0.26-0.31% V2O5 at the average) and a large depth of the occurrence.

Resources and output

At present, the magnetite-ilmenite ores appear to be of an interest mainly as a vanadium raw material. According to M. Nieć (2003)* the cut-off grade equivalent of V2O5 in an anticipated economic ore should be equal 0.73% - with such assumption the resources of the Suwałki region would constitute only 1% of the resources previously documented. Large resources of shallow-seated or even exposed deposits of that type recently discovered and proved in several places throughout the world, especially in the Republic of South Africa, indicate that the potential development of the Suwałki area ore deposits cannot be expected in the foreseeable future. According to the quoted author, the classification of the ores “even as sub-economic seems to be too optimistic under the present conditions. The potential exploitation is assessed to be extremely conflictual. The ores should be treated as an interesting geological object, without any practical value”. Taking it into account, it can be said that in Poland there is lack of iron ores deposits possible to development and exploitation.

The documented bog iron ore deposit Dębe Małe with resources estimated at 8 thousand tonnes is intended to other industrial uses than the steel industry, especially as an adsorbent of H2S, CO2 and organic compounds of sulfur and other environmental activities.
