Magnetic separation can recycle small amount of ferrochrome, but in the process of magnetic separation adsorption with large quantities of iron slag, lead to sharp decline in the purity of ferrochrome, depending on the chromium content in chromium iron alloy its permeability also is not the same, but the magnetic iron is contained in the slag, lead to the failure of the magnetic separation .
Feb 25, 2009· There are many means of separating mixtures in chemistry. One such method is not very common, but takes advantage of the magnetic properties .
The flue dust generated in the ferrochrome industry is one particular waste containing chromite mineral deposits. The toxic character of trivalent as well as hexavalent chromium can make the flue dust in the ferrochrome industry dangerous.
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.

Introduction to Chromium Jigging Equipment. 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 all. The gravity separation can be the only way for ferrochrome recovery.
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.
magnetic separation. The first stage of slag processing is crushing and sc reening the feed material to fractions of 04 and 422 mm. Coarser fractio ns are handled by a heavy media separation .
The densities of ferrochrome and slag are 6800 kg/ m3 and 2800kg/ m3 respectively hence gravity separation method in water medium can be done.
Sep 08, 2019· Magnetic separation is an industrial process where ferromagnetic contaminants are recovered from materials on the production line. Manufacturers use this to extract useful metal, separate recycling, purify materials, and perform a wide variety of other tasks. Manufacturers of magnetic separation equipment may have a range of products available ...
Magnetic separation is an important beneficiation process and is usually adopted for ores of manganese, phosphate, titanium, chrome, tungsten, molybdenum, nickel, bauxite and niobiumtantalum ores in addition to iron ores .Magnetic separation methods were also carried out for the ferrochrome industry wastes such as the flue .
Samancor was created in 1975 and its Chrome Division grew, mainly by acquisition, to become the world's largest integrated ferrochrome producer and South Africa's leading exporter of chemicalgrade chromite and foundry sand.
Jan 06, 2005· The magnetic separation was carried out in a dry belt magnetic separator in which the magnetic roll assembly consisted of a motor driven magnetic roll, .
Ferrochrome smelting slag processing line is mainly to recover the valuable ferrochrome alloys from the slag in a forms that will be as far as possible directly saleable. This production line is now producing saleable ferrochrome containing less than 2% slag at a recovery of over 96% of liberated metal.
