ferrochrome slag ore beneficiation process introduction

20171012&ensp·&enspferrochrome slag ore beneficiation process introduction and flowchart. chromium slag is waste residue containing chromium when pyrometallurgical smelting ferrochromium alloy at present mainly produce by using submerged arc furnace to produce high carbon ferrochrome.the main component of chromium slag is chromic oxide silicon oxide magnesium oxide alumina calcium

a beneficiation study on a low grade iron ore by gravity

the results indied that spiral separation yields higher separation efficiency than others. the combination of spiral and multi gravity methods showed that the grade and recovery could be obtained 58.7 and 55.6% respectively. scrubbing and desliming stages increased the recovery in the wet high intensity magnetic process.

introduction to chromium jigging equipment

2017216&ensp·&enspthe jigging equipment must be used because the permeability of most of ferrochrome is not good. but some lowchromium alloy have good magnetic permeability. the waste slag has good magnetic permeability because the ferrochromium slag contains unreduced iron oxide and chromium oxide. so magnetic separation method can not recover ferrochromium at

ferrochrome smelting slag gravity separation technology

20181010&ensp·&enspferrochrome smelting slag gravity separation technology. ferrochrome smelting slag is also known as ferrochrome slag and chromium slag etc. are produced by the smelting ferrochrome solid waste residue. ferrochrome slag is mostly solid dry slag hardness is very big is gray black according to the different of smelting process ferrochrome smelting slag containes different chromium iron

recovery of alloy from ferrochrome slagferrochrome

20191017&ensp·&enspspecific gravity of ferrochrome 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. gravity separation mainly separates useful minerals or metals on basic of specific gravity difference between minerals or metals and wastes.

study cronimet mining

2017123&ensp·&enspduring the project lifetime in excess of 150 000 tonnes of ferrochrome slag was processed where the feed material consisted of 2.72% free ferrochrome. in addition the high grade concentrate which resulted was produced through the deployment of sensorbased sorting as well as gravity separation and magnetic separation technologies.

production characteristics and use of

2015522&ensp·&enspthe density of the ferrochrome slag is between 2.5 2.8 g/cm 3 and that of ferrochrome 6.8 g/cm 3. the viscosity of slag is a function of the pressure and temperature. the viscosity also has an essential meaning in the separation of slag and metal. the viscosity of the fe rrochrome slag will increase when the content of sio 2 and

20101112&ensp·&enspmagnetic separation impossible. thus the concentration of this ore was found to be useless. therefore the study was carried out on the low grade chromite ore without concentration. 2 experimental pilot plant experimental heats were carried out to produce extralow carbon ferrochromium from a

effect of basicity on beneficiated chromite sand smelting

in this present study ferrochrome was derived from indonesian chromite sand with lowgrade cr/fe ratio. in order to improve the ratio beneficiation process such as premagnetic separation and reduction process at 1000°c for 60 minutes was required.

chromite wikipediachinese

20191016&ensp·&enspchromite ore can be mined to produce chromite concentrate. it can also be crushed and processed. chromite concentrate when combined with a reductant such as coal or coke and a high temperature furnace can produce ferrochrome. ferrochrome is a type of ferroalloy that is an alloy in between chromium and iron

the method of separation is on a particle by particle basis and is hence used as a benchmarking tool for magnetic separation. the frantz is typically used to provide detailed accurate fractionation of mineral samples with similar magnetic susceptibilities such as titaniferous magnetite and

the recovery of ferrochrome from slag at zimasco

the results of this initial testwork identified magnetic separation and jigging as potential methods for recovering this metal from crushed slag. the metal was crushed to coarse sizes (<75 nun) at which metal concentrate grades of about 93 per cent could be obtained from magnetic separation and handsorting to remove unliberated metal.
