There are alloy granules of different size in the chromite smelting slag, and people in this industry know the method and equipment involved to recover these alloy granules. Specific gravity of alloy is much bigger than that of slag, so gravity separation will be the ideal and high efficient way to get the alloy granules attached to the smelting slag

Apr 13, 2021 A study of copper slag smelting indicates that there is value in characterizing copper slag with view of recovery of viable metals, especially iron. Analysis from the results showed that nickel, iron and copper existed in high amounts in the slag with these elements found in the fayalite and chromite
Jul 14, 2020 Inference on Beneficiation Results of Low-Grade chromite Ore. The beneficiation studies of low-grade chromite ore from Ghutrigaon reveals that it can be upgraded through physical beneficiation methods. Following gravity concentration technique, a feed of 16% Cr 2 O 3 can be upgraded to 40.1%, with 23% yield, 58% recovery and Cr/Fe ratio of 3.35
Jun 15, 2015 Ferro-chrome is one of the most important ferro-alloys and is produced from chromite, an iron chromium oxide, FeCr2O4. Chromite is important because it is the only economic ore of chromium, an essential element for a wide variety of chemical and manufactured products and the aforementioned ferro-alloy
process for the beneficiation of titaniferous ores wherein the natural ore is oxidized to convert substantially all of the iron values present to the ferric state and the oxidized ore is then deoxidized to convert substantially all of the iron values therin to the ferrous state and the product in which substantially all of the iron values therein are in the ferrous state containing not more
Aug 05, 2016 A high-temperature reduction and smelting process was used to recover iron and calcium aluminate slag from high-ferrous bauxite. The effects of w(CaO)/w(SiO 2) ratio, anthracite ratio, and reduction temperature and time on the recovery and size of iron nuggets and on the Al 2 O 3 grade of the calcium aluminate slag were investigated through thermodynamic calculations and experiments
Chromium is largely used as alloying elements in steels for production of stainless steels. It is added in form of ferro-chromium, which is presently imported from Russia and Germany to meet the need of Nigerian Steel Industry. Chromite ore (FeOCr2O3) is the most important mineral occurrence of chromium, and some deposits are reported in Anka Local Government Area of Zamfara State
Jan 01, 2016 Chromite (Cr) occurs exclusively in mafic and ultramafic igneous rocks (Papp and Lipin, 2006).Although some Cr-based minerals such as crocoite (PbCrO 4), vauquelinite (Pb 2 Cu[CrO 4][PO 4]), uvarovite (Ca 3 Cr 2 [SiO 4] 3), and merumite (4(Cr,Al) 2 O 3 3H 2 O) are well known, chromite (FeCr 2 O 4) is the only one that is a commercially recoverable source of Cr (Sueker, 2006

Ferro chrome slag may contain chromium in +3 and +6 oxidation states. Separation and determination of chromium content of the slag samples collected from Jindal Ferro Alloys Corporation, (Kottha
es, ferrochrome alloy and slag, are tapped into ladles at 2.5 hour intervals. The ferrochrome slag production is 1.2 t / t FeCr. It is mainly granulated and the rest is air-cooled. There is an in-house special handling and metal recovery process for the air-cooled slag, where it is made into finished products. In addition to recov
