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.
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
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

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.

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.
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

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.
characterisation and liberation of chromium from fine ferrochrome waste materials. magnetic separation dense media separation (dms) flotation shaking tables and spirals (e.g. sripriya and murty 2004 shen and forssberg 2002 coetzer et al. 1997 visser and barret 1992). these processes have also predominantly been limited to the
a magnetic separation may also be inserted after the solid state reduction step prior to the aeration step. the procedure results in a better than 80 % recovery of the tio2 content and the removal of about two thirds of the cr2o3 content. wo1990004656a1 refining of ilmenite by removal of excess chromite google patents
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 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.
