This paper present the results of a preliminary study to assess the potential of the visible, NIR and SWIR energy of the EMR in differing iron ores of different grades in a rapid manner using hyperspectral radiometry. Using different iron ore samples from Noamundi mines, Jharkhand, India, certain spectro-radiometric measurements and geochemical analysis were carried out and the results have bee...

Qara Aqaj titanium potential is one of the two major known titanium resources in Iran. The main host rocks of the ore body are ultramafics including wehrlite and lherzolite with minor clinopyroxenite. Qara Aqaj intrusion is composed mainly of ultramafic-mafic rocks, layered gabbro, diorite, microdiorite and some monzonite and alkali syenite. This intrusion has intruded the basement complex (amp...

We present a first paragenetic study of the Wuyier, Wuyisan, Wuyiyi and Shihongtan sandstone-hosted roll-front uranium deposits, northwest China. The mineralization is hosted by Lower–Middle Jurassic coarseto medium-grained sandstones, which are dark-gray to black due to a mixture of ore minerals and carbonaceous debris. The sandstone is alluvial fan-braided river facies. Minerals associated wi...

Bauxite is mined and transported by conveyor to a processing plant, screened and washed, then placed into blended stockpiles to feed the alumina refinery. While being stacked to the stockpile, the ore is sampled. Completed stockpiles must be acceptably close to target grade (composition), not only in alumina, but also in residual silica, carbon and sodium carbonate. The mine is an open-cut pit....

The objective of this research is to determine all processes in the magmatic evolution and related hydrothermal activities that created the volcanic rocks and associated ore-forming systems of the Bafq ‎mining district. Several iron oxide-apatite (IOA) deposits were investigated in this area with a focus on the Sechahun ore deposit. The Bafq ‎mining district is well known for hosting significan...
