DOI: 10.1016/j.oregeorev.2019.102995
Abstract: Abstract The Mt Richardson deposit contains high-grade (>57 wt% Fetotal) iron ore zones hosted by several banded iron-formations (BIFs) in the c. 3504 Ma Illaara greenstone belt. The BIFs and intervening mafic igneous rocks are exposed along… read more here.

DOI: 10.1021/acsomega.1c00129
Abstract: Analysis of the current technical solutions for the processing of iron ores showed that the high-grade ores are directly exposed to metallurgical processing; by comparison, low-grade ores, depending on the mineralogical and material composition, are… read more here.

DOI: 10.1139/cjes-2018-0183
Abstract: Rock magnetic measurements were carried out on drill core material and hand specimens from the Blötberget apatite – iron oxide deposit in the Bergslagen ore province, south-central Sweden, to characterise their magnetic properties. Measurements included several kinds… read more here.
