Low carbon ferrochrome is a primary alloying element in the production of stainless steel. The Mixing Method (Perrin and Duplex) processes are most commonly used for the production thereof. However, during the cocktailing step, process temperatures are extremely high, resulting in rapid deterioration of the ladle refractories and fuming of the products. The high temperature .
If the dehydrating process of dihydrate gypsum is in a dry environment lacking water steam, then β − CaSO 4 · 1 2 H 2 O is produced, called common building gypsum, and α − CaSO 4 · 1 2 H 2, high strength building gypsum, ß type hemihydrate gypsum is irregular scaly secondary particles, which are made up of very small single crystals, a type hemihydrate gypsum is made up of .
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 DWPmethod. A magnet separator and spiral washing are used for finegrained material. The recovered alloy of 04 and 422 mm are saleable products. The slag products from the process are aggregates of .
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. For this processing line, not only the smelting alloy can be recovered, but .

Ferrochrome slag (FS) is another residue that is obtained as a solid waste by the smelting process during the production of stainless steel in Ferroalloy industries. FS possesses the required engineering properties of coarse aggregates. The possibility of using FA with lime for partial replacement of ordinary Portland cement (OPC) and FS for total replacement of natural .
· /l. Also, reduction of Cr(VI) to Cr(III) and a subsequent precipitation of Cr(III) by using ferrochrome slag (FS) in a model solution has been aimed. The effects of amount of acid, contact time, FS dosage, initial Cr(VI) concentration and temperature on the Cr(VI) reduction have been studied through the batch runs. The amount of acid has been found to be the most .
