Beneficiating Ironveld unveils plans for large new pig ...

their magnetite with high quality hematite sourced from Australia, to dilute the TiO2, hence reducing the risk of hearth precipitation. In the 1960s, this was not deemed possible. The smelting of hot pre-reduced titaniferous magnetite iron ore to produce pig iron and a vanadium rich slag was started in the 1960s by both Highveld and

Development of a control strategy for the open slag bath ...

Magnetite is an iron ore used in making wrought iron and pig iron. Magnetite rocks are a dull, dark gray and are very hard to tell apart from cassiterite and galena. Magnetite spawns as small rocks on the surface, indicating a vein somewhere below.

Jan 31, 1978· Such pig iron is commercially available from several sources, for example, Highveld pig iron from South Africa normally contains somewhat more than one percent vanadium. Suitable vanadium-containing pig iron may also be produced by adding vanadium-containing materials to iron ore having an insufficient concentration of vanadium.

Jun 06, 2006· Highveld's method of smelting the magnetite ore involves a preliminary "pre-reduction" stage. ... The hot sponge iron is then melted continuously in an electric arc furnace to produce pig ...

(PDF) Introduction to the production of clean steel

The outcome of the study included the identification of industrial opportunities to produce pig iron, vanadium redox batteries as well as titanium pigment from the bushveld magnetite deposits. Amongst the identified opportunities was the Nyanza Light Metals project, developed to produce titanium pigment utilising the Evraz Highveld Steel waste ...

Highveld Industrial Park

Titaniferous magnetite (titanomagnetite) is typically processed by smelting to produce vanadium-bearing pig iron and titania (TiO 2)-bearing slag, which is generally discarded as waste. The discard slag at Evraz Highveld Steel and Vanadium Corporation (EHSV) contains about 0.9% V 2O 5 and 35% TiO 2 (Steinberg, Geyser, and Nell, (2011).

pig iron has been established in "Tatara" furnace.5)The "Tatara" is a Japanese traditional process for making main-ly molten pig iron with steel bloom from iron sand and charcoal in a box type furnace with 1.2m heights. The "Tatara" had been commercially operated until 1922. The productivity of molten pig iron and steel bloom depends on

Vanadium Resources in Titaniferous Magnetite Deposits

South Australia has a significant and continuous history of iron ore mining, commencing in the late 1800s to provide hematite flux for the Broken Hill smelting operations. The first smelting of iron ore to produce pig iron occurred in 1873 from the Mount Jagged deposit, located 52 km south of Adelaide.

Processing of vanadium: a review - ScienceDirect

and anthracite coal to produce pig iron with 3.5 wt.% C and about 1.2 wt.% V. The tapped smelter slag contained 32 wt.% TiOz and 0.9 wt.% VzOs. The smelter gas (i.e., a mixture of CO and Hz) is typically reused elsewhere in the plant, but in fine the combustible gas ends up burned releasing C02 into the atmosphere.
