Ferroalloy is the material necessary formetallurgical industry, used for doping, deoxidation, refining of ferrous and non-ferrous metals. The ferroalloy is based on an alloy of iron (Fe, ferrum) with additives (manganese, potassium, molybdenum, silicon, etc.). Production takes place in special units.

Ferroalloy processes are divided into continuous and periodic. Continuous processes are characterized by continuous loading of the charge and periodic (or continuous) slag and ferroalloy tapping. The charge is in the furnace at a certain level throughout the process. The electrodes are immersed in a charge continuously.
The advantages of plasma technology in Ferroalloy production are direct processing as poor ores and charge, almost entirely consisting of fines and dust, the use of coal instead of the more expensive metallurgical coke, ensuring optimal thermodynamic and kinetic conditions of the reactions, improve the technological process.
We propose a flow diagram for processing ferroalloy production waste, such as silicothermic slag from manganese metal, as well as wet and dry powder of cleaning gas from ferroalloy furnaces that smelt manganese alloys. We experimentally determined the parameters for intensifying the calcium chloride method of enriching ferroalloy production waste, which .
Jul 14, 2020· The low-grade siliceous chromite ore from Ghutrigaon, Odisha, India, containing ~ 16% Cr2O3, with Cr/Fe ratio of 1.97 and ~ 55% of SiO2, does not find any use in metallurgical industry and hence considered as waste. Mineralogical investigation indicates the presence of chromite and quartz as major minerals with minor fuchsite and kaolinite. The beneficiation studies reveal that the product can ...

Our process design is based on successes achieved and lessons learned from the many plants built in the past. Utilising our vast process development, design and project engineering capability and extensive operating experience, our plants ensure optimum capital and operating costs for high recovery of on-specification ferroalloy from the slag.
Recovery of metal from slag/mixed metal generated in ferroalloy . Virtually all charge chrome plants now use the crushing/jigging process to Tata Steel to develop a flow sheet for the recovery of metal from metal–slag mix Processing and Reusing Technologies for Steelmaking Slag. The iron/steel slag processing flow is schematically shown in ...
Figure 1: Electric furnace used in ferroalloy production. Exothermic (Metallothermic) Process. The exothermic process is generally used to produce high-grade alloys with low-carbon content. The intermediate molten alloy used in the process may come directly from a submerged electric arc furnace or from another type of heating device.

The largest suppliers of slag for processing are ArcelorMittal Kryvyi Rih and UMG, which was founded by SCM in 2006 to manage raw material assets. Metallurgical slag is divided into several types: blast-furnace, steel and ferroalloy. Blast furnace slag is the most popular in Ukraine: it is a byproduct of pig iron smelting in a blast furnace.
ulation process is shown in Figure 5. 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
A method of processing a ferroalloy waste slag in a reactor which includes the steps of treating the slag with a metallic reductant and a conditioning flux to release a metal oxide and reduce it to metallic form, to use as a commercially acceptable silicon-containing alloy and to form a waste slag which is detoxified by means of granulation and separating the detoxified slag from .
