Magnetite ore–coal composite pellets with about 10, 15 and 20mm diameter were rapidly smelted to produce pig iron by microwave heating in N 2 gas. A microwave generator with 5kW maximum power at 2.45GHz was employed. Carbon content in pig iron was about 2mass% near the liquidus line in the Fe–C system. Slag was easily separated from pig ...

Pig iron is an intermediate product of the iron industry in the production of steel, also known as crude iron, which is obtained by smelting iron ore in a blast furnace.Pig iron has a very high carbon content, typically 3.8–4.7%, along with silica and other constituents of dross, which makes it very brittle and not useful directly as a material except for limited applications.

The trials conducted by Highveld Steel Development Company Limited on the viability of processing titaniferous magnetite ore to produce liquid pig iron and vanadium-bearing slag were a success [59
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). The vanadium content in the discard slag is relatively ...
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
Highveld ore) is run by Panzhihua Iron and Steel in China2. They do, however, blend their magnetite with high quality haematite 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 prereduced titaniferous magnetite iron ore to produce pig iron and a vanadium rich slag was started in the 1960s ...
06/03/2013 Magnetite concentrate and fine wood were combined together to produce pellets composed of 80% magnetite concentrate and 20% fine wood by weight, using a pelletizing drum. The pellets' composition was based on the Fe 3 O 4:C ratio (carbon requirement to reduce iron oxide into iron). A pelletizing drum with the following procedure was used to combine the magnetite and wood

06/06/2006 The sponge iron is melted in electric resistance smelters for further reduction to produce molten pig iron. The pig iron is tapped into ladles for hot charging into the steel plant. Prior to ...
31/01/1978 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. For example, the titaniferous magnetite ore of the
technology with the Highveld ore TiO2 content reaching 12.6%. The smelting of hot pre-reduced titaniferous iron ore to produce pig iron and vanadium-containing slag for the production of vanadium products was started in the 1960s by both Highveld Steel and Vanadium, and New Zealand Steel (NZS).
Ferro Vanadium was primarily recovered from titanium-bearing magnetite ore processed to produce pig iron. The process produces a slag containing 20% to 24% vanadium pentoxide, which can be further processed to ferrovanadium containing 40% to 50% vanadium. 84% came from ferrovanadium and nearly all of it (99%) went into steel manufacturing.
In 1934 Bleloch had outlined a method for the extraction of vanadium and pig iron from vanadiferous magnetite. ... During this period he was Technical Adviser to Rand Mines Limited on a project to construct a commercial plant to produce chromium steel from Bushveld ore. The Evraz Highveld Steel Vanadium (EHSV) process flowsheet was developed in the early 1960s, based on Bleloch's 1949
Ironveld expects to mine 2.4 million tons of magnetite a year as feedstock for its eventual million-ton-a-year pig-iron plant, which will also produce vanadium and titanium byproducts. The initial ...

Highveld continued to supply ore to Vanchem from its Mapochs mine in Limpopo until it closed in 2015. Without guaranteed ore supply from Mapochs, Vanchem was forced into Business Rescue in November 2015 with the Vanchem plant being put into care and maintenance later that year. The plant was partially re-started in the third quarter of 2018, after Vanchem was able to procure magnetite ore from ...
The Highveld Development Company Limited was established on 19 May 1960 to investigate the viability of processing titaniferous magnetite ore for the production of liquid pig iron and vanadium-bearing slag. In November 1964, the company embarked on a programme to build an integrated iron and steel works near Witbank. The name of the
