Heating ores to elevated temperatures is called roasting, and it causes the oxygen in the air to convert the sulfur in the ore to sulfur dioxide, which is a gas and is emitted to the air. The process works best when the ore is crushed to small pieces before roasting.

2017-4-14 · TITANIFEROUS MAGNETITE AND VANADIUM PROJECTS Osho has been involved in the development of magnetite and vanadium ore projects in the provinces of North West and Limpopo in South Africa.
These ores generally comprise a magnetite spinel in which titanium is present in solid solution as ilmenite or ulvospinel and vanadium is present in solid solution as the spinel structure coulsonite.
Magnetite Facts & Figures | The Magnetite Network The main iron mineral in magnetite ore is the ferrous iron Strong global demand for steel has seen magnetite ore''s increased share of Australia''s
Significant titanium-bearing ilmenite deposits exist in Western Australia, Canada, China, India, Mozambique, New Zealand, Norway, Ukraine and South Africa, while rutile deposits are found in South Africa, India and Sierra Leone.
2018-10-10 · Another, minor, source of iron ores are magmatic accumulations in layered intrusions which contain a typically titanium-bearing magnetite often with vanadium. These ores form a niche market, with specialty smelters used to recover the iron, titanium and vanadium.
Although there is evidence of the bloomery smelting of magnetite sands elsewhere in sub-Saharan Africa, and occasional reports from elsewhere (Japan, Korea, Taiwan, Macedonia and the eastern United States), this is the first published study to report the smelting of high-titanium iron ores.
2018-10-9 · Vanadium is mined mostly in South Africa, north-western China, The vanadium ends up in pig iron produced from vanadium-bearing magnetite. Depending on the ore used, the slag contains up to 25% of vanadium. Vanadium stabilizes the beta form of titanium and increases the strength and temperature stability of titanium.
2012-11-30 · Some researchers have found satisfactory reducibility via the oxidation route of titanium bearing magnetite ore followed by reduction ( Samanta et al., 2014).
Furthermore, a majority of the supply feedstock from China comes from steel plants that process low grade vanadium bearing magnetite ores to produce steel and a vanadium slag which is then further processed through a process similar to the primary production processes –
US4389164A - Automatic liquid level controller - Google A source of acoustic pressure pulses is coupled to the surface casing of a well so that they are transmitted down the well and reflected by the gas-liquid interface.
Remote sensing has the potential to be a big part in loing magnetite sands as even small amounts of magnetite in sand can drastically alter the sands albedo which is the amount of electromagnetic radiation the sand will reflect.
