RECENT investigation of samples labelled zaratite from the Lord Brassey Mine, near Heazlewood, Tasmania, in the mineral collection of the Museum of Victoria revealed the presence of the rare nickel carbonate, otwayite, and the rare nickel hydroxide, theophrastite. X-ray diffraction, electron microprobe and infrared analysis were utilised in the study, which failed to confirm the presence of zar...

Out of a total of 79 employees at a factory making vanadium pentoxide from magnetite ore 63 were investigated by respiratory questionnaire, chest radiography, and tests of ventilatory function. The findings were compared with a reference group of 63 men, matched for age (to within two years) and for smoking habit (to within five cigarettes daily) selected from workers at a magnetite ore mine. A...

In this study, enrichment possibility of apatite-bearing iron ore sample was investigated to obtain and phosphate concentrates, separately. It determined that the raw contains 35.75% Fe 5.36 P2O5. Magnetite from can be enriched with low field strength wet magnetic separators, apatite magnetite residues by flotation. For purpose, ground minus 106 m size then subjected separation following Accor...

Magnetic properties of sediments were investigated in 7 gravity cores recovered along a transect of the Mandovi estuary, western India to understand their provenance and pollution. The maximum magnetic susceptibility of sediments was at least 6 times higher in the upper/middle estuary than in lower estuary/bay. The χfd% and χARM/SIRM of sediments indicated coarse, multi-domain and pseudo-single...

This paper provides a review of the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER), Advanced Land Imager (ALI), and Hyperion data and applications of the data as a tool for ore minerals exploration, lithological and structural mapping. Spectral information extraction from ASTER, ALI, and Hyperion data has great ability to assist geologists in all disciplines to map the d...

The paper considers the results of application dry magnetic separation on samples ferruginous quartzites Kostomuksha ore field, represented by refractory ore, free-milling and their mixture. assessment influence texture technological parameters indicates insignificant changes: yield non-magnetic product varies from 12.4 to 13.5%, Fetotal content in increases 1.11–1.14 times. A decrease at least...
