(57) Abstract: Use: for processing slag dump of Ferroalloy production in the metallurgical and other industries. The inventive method for processing a mixture of solid slag metallurgical production includes crushing, sieving slag into small, medium and coarse, magnetic separation of the fine fraction, magnetic separation medium fractions, subsequent pneumatic separation medium fractions and ...
The ferroalloy separation from the lumpy slag happens in a special process, which is based on a gravity and magnetic separation. The first stage of slag processing is crushing and sc reening the feed material to fractions of 0-4 and 4-22 mm. Coarser fractio ns are handled by a heavy media separation - the DWP-method.

Ferrochrome is an important alloy in stainless steel making due to its contribution to high strength and corrosion resistance. In this present study, ferrochrome was derived from Indonesian chromite sand with low-grade Cr/Fe ratio. In order to improve the ratio, beneficiation process such as pre-magnetic separation and reduction process at 1000°C for 60 minutes was required.
Process Of Iron Slag Seperation Machine. 20-10-2016· Magnetic separation of iron from zinc slag. Smelting . smelting is a process of applying heat to ore in order to melt out a base metal.it is a form of extractive metallurgy.it is used to extract many metals from their ores, including silver, iron, copper, and other base metals.smelting uses heat and a chemical reducing agent to decompose ...
For the carbon steel slag, originating from an EAF, three particle sizes were studied (0-5 mm, 20-40 mm, 40-185 mm). The ferrochrome slag was crushed and sieved to a 4-9 mm fraction. The stainless steel slag is a finegrained fraction (< 500 µm) obtained after a crushing, screening and demetallisation treatment. For the characterization
The magnetic separator has the advantages of simple structure, large processing capacity, convenient operation and easy maintenance. The process of the equipment is to finely crush the ore to 5mm or less than 3mm, and then use the permanent magnetic midfield magnetic separator to perform the magnetic separation of the wet magnetic separator.

Ferrochrome slag Recovery Solution. 1.What is the Ferrochrome slag. Ferrochrome slag is a by-product from the production of ferrochrome, an essential component in stainless steel. There is a certain amount of ferrochrome alloy in the slag. Recycling the alloy in slag can not only reduce the waste of valuable resources, but also get rich returns. 2.
The most common recovery process is to crush the slag (in the case of the first slag-handling method) and recover the alloy particles in a wet jigging process. In particular cases where the high carbon ferrochrome is sufficiently magnetic, magnetic separation techniques can also be applied. The quality of the product from the recovery process ...
Specific 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.
steel slag magnetic separation k-vier Steel slag, a by-product of steel making, is produced during the separation of the molten steel from impurities in steel-making furnac The slag occurs as a molten liquid melt and is a complex solution of silicates and oxides that solidifies upon cooling,This metals recovery operation (using magnetic
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 hand-sorting to remove unliberated metal.
magnetic separation impossible. Thus, the concentration of this ore was found to be useless. ... The reactor was emptied and the produced metal and slag were weighed. Representative samples were then selected for the determination of the alloy and slag chemical compositions.
A direct reduction process for the production of ferrochrome from chromite ore or concentrate is disclosed. According to the present invention, calcium chloride (CaCl2) is added as a catalyst to accelerate the solid reduction and enhance the particle growth of the metallic phase (i.e. ferrochrome) during reduction. The reduction of chromite ore or concentrate takes place at much lower ...
Ferrochrome slag wash plant/metal recovery plant is used to recover alloy from ferrochrome slag.During discharing the slag from submerged arc furnace, there are some alloy mixed in the slag. recovery the plant can not only reduce the waste of good products,can also get a rich profit. many alloy companies begin to set up the metal recovery plant.
When studying the characteristics and the possibility of utilization of high-carbon ferrochrome slags, the authors of [] found that the major part of chromium exists in such magnetic materials as iron–chromium spinel and ferrochrome.The particle size and the current were found to be two factors that significantly affect the efficiency of magnetic separation.
