In this paper the analysis of the processes for spontaneous decay of slags from the production of refined ferroalloy grades is performed. It is shown that the main reason for the decay is the formation of a dicalcium silicate in highly basic melts with CaO / SiO2 ratio of Based on the performed studies, three main promising directions for the stabilization of slags of ferroalloy ...

collects in a top layer, and a middling layer is The situation has changed since, and slag dumps sandwiched between the bottom and top layers. worldwide have grown to such an extent, that Layering of the randomly mixed slag grains by appropriate metal recovery plants now need to process density in the jig is based on the wellknown principle ...

This paper presents basic principles of the process and its applications for recovery of metals from slag, especially ferroalloys. A commercial jig plant has been installed in South Africa to recover metal concentrate of 97% grade at 76% metal recovery from minus 1mm ferrochrome slag far exceeding conventional gravity methods.

A method is provided for continuous smelting of ferrochrome with less than % by weight carbon content in an electric reduction furnace. In the described method, separately from the normal mixture of ores continuously fed into the melt, and consisting of lumpy ore agglomerated fine ore, part of the mixture of ores is introduced as wholly or partially unreduced oxiderich chrome ore directly into the .

Steel industry byproduct, ferrochrome slag, was analysed by laser diffractometer, SEM/EDS, XRD and thermal analysis to find out its characteristic properties in order to be utilised as raw material in the manufacturing of novel refractory castables.

process water of metal recovery from slag, (Coetzer, Giesekke and Guest, 1997) it has been reported that Cr has been detected as chromate in the processing water, which may create chromium pollution. The milling practice of ferrochromium slag alters the oxidation state of chromium, releasing Cr (VI) into the environment (Buekes and Guest, 2001).

A ferrochrome converter (CRC) is used for removal of silicon and carbon from ferrochrome in stainless steel production. The raw materials are molten ferrochrome and stainless steel scrap, and the process produces a raw material for argonoxygendecarburization (AOD). The zinc content prevents the utilization of CRC dust (CRCD).

The Recovery of Chrome and Manganese Alloy Fines from Slag. recovery of ferrochrome metal possible from the Apic classifier. The method to measure metal grade from slag in gravity separation was to look at liberated metal. To do this a modal analysis was employed by using the point counting method. The client needed 90% ferrochrome metal in .

The possibility of obtaining a nondisintegrating slag during melting lowcarbon ferrochrome with subsequent processing into building rubble will make it possible to improve the ecological situation in the vicinity of ferroalloy enterprises, to reduce slag dump and adjacent territory contamination and dust content, and also to reduce the amount of slag, loss of chromium, and to increase productivity of the .

In metal analysis, ICPOES or AA is often used to determine the metal contents in industrial products and ores, but the standard dissolution method used for ferrochrome and chromite is a multiacid digestion process which is laborious, time consuming, and needs the use of HClO 4, HNO 3 and HF acids.

The Slag Detection System (SDS) delivers improved yields, higherquality steel and reduces costly downstream processing.
