Jul 18, 2012 The extraction of vanadium from high calcium vanadium slag was attempted by direct roasting and soda leaching. The oxidation process of the vanadium slag at different temperatures was investigated by X-ray diffraction XRD, scanning electron microscopy SEM, and energy dispersive spectroscopy EDS. The effects of roasting temperature, roasting time,
With more extensive application of shaking ladles in producing ferroalloy, the investigation on the equipment and process of shaking ladles is reviewed and the motion of two-phase flow is analyzed. Some issues related to the use of shaking ladles, which need to be further explored, were pointed out to direct the design of large shaking ladles.
Carlos Thomas, ... Francisco Agrela, in New Trends in Eco-efficient and Recycled Concrete, 2019. 7.1.2 Types and classification of steel slags. Steel slags SSs are usually classified according to the type of furnace in which they are produced. The properties of the slag depend on the type of process used to produce the crude steel, the cooling conditions of the slag and the valorisation process.

The addition of lime supports slag formation. After completion of the blowing process, the slag and pig iron are separated by tapping the convertor. The converter is tilted into the tapping position for this purpose. The melt is guided into a steel ladle via the tap hole. The slag is retained in the converter and subsequently re-utilised.
The invention belongs to the technical field of ferrous alloy smelting, in particular to a production method of low-phosphorus micro-carbon ferro chrome. The production method comprises the following steps feeding silicon-chromium alloy and ferro chrome to an electric arc furnace to smelt for 10-20min, feeding lime after the silicon-chromium alloy and the ferro chrome are molten for
vanadium from the ore hence producing two major sources of income for the company. At the Iron Plant the goal is to maximize the reduction of vanadium oxide into the liquid iron, and producing maximum tonnage of liquid metal. The vanadium in the liquid iron is then re-oxidized at the Steel Plant through the shaking-ladle process.

Development of the process for production of vanadium rich slag and low silicon pig iron from vanadium bearing titaniferous magnetites of Masanikere at VISL, Bhadravati By ... absence of a shaking ladle to produce vana-dium rich slag, it was proposed to carry-out oxy-gen blowing to the level of 12 to 15 tonnes per
slag is one of the most important sources of vanadium, which accounts for 58 for the production of vanadium 2. The main processes for production of vanadium slag include shaking ladle process, hot metal ladle process and converter process 34. The representative vanadium extraction route mainly consists of the
The present invention concerns a method for producing calcium carbonate containing the steps of extraction of alkaline industrial waste or by-products using as a first extraction solvent an aqueous solution of a salt formed from a weak acid and a weak base, whereby a vanadium-enriched first residue is allowed to settle and a calcium-rich first filtrate is formed, filtration, whereby the first ...
This specific consumption was estimated based on limited data addressing the blowing of pig iron to produce vanadium pentoxide products and it includes crushing, grinding, and one or more of the following roast-leach, rotary-kiln, electric-smelting, shaking-ladle
An improved method is described for processing pig iron containing vanadium to obtain a slag containing at least 8 percent vanadium and having a vanadium to iron ratio of at least 0.5 which is directly useful as a refining agent for producing ferrovanadium alloys, the improvement residing in simultaneously introducing a highly oxidizing gas and a protective fluid below the upper
Nov 23, 2017 This specific consumption was estimated based on limited data addressing the blowing of pig iron to produce vanadium pentoxide products and it includes crushing, grinding, and one or more of the following roast-leach, rotary-kiln, electric-smelting, shaking-ladle, and basic-oxygen-furnace operations.
The slag from the shaking ladle oxygen blowing operation contains the bulk of the vanadium, typically about 14 percent vanadium by weight but, as noted above, the vanadium to iron ratio of such Highveld slag is less than the level of 0.5 needed in the refining operation of the Rathmann et al. process, being typically about 0.4.
