Pyrometallurgical Process - an overview | …
The pyrometallurgical process serves for the generation of cast vanadium concentrate (CVC) from which high purity vanadium chemicals are extracted. At SCR, spent metal catalysts and metal residues containing Ni, Co, Mo, V, and W are processed to reclaim the metals. Process details are not available for this plant [697].
Pyrometallurgical Processes and Equipment
pyrometallurgical unit operations. In addition, the data can be used to model the performance of the operations. Examples include the deportment of elements between process streams, or the solubility of chromium in matte smelting furnaces. Equipment Feed preparation and pre-treatment • 0.2 t/h and 2 t/h externally heated rotary kilns for dry-

Pyrometallurgy - Wikipedia
Pyrometallurgical processes are generally grouped into one or more of the following categories: [citation needed] calcining, roasting, smelting, refining. Most pyrometallurgical processes require energy input to sustain the temperature at which the process takes place. The energy is usually provided in the form of combustion or from electrical ...

An Introduction to Pyrometallurgical Technologies
Pyrometallurgical routes are used in the commercial production of steel, aluminium, metallurgical silicon, manganese, chromium, titanium, and many other metals and alloys. The significant energy consuming processes in metals extraction are the reduction and smelting stages with formation of two immiscible phases – molten metal and the predominantly metal oxide phase, slag.
Pyrometallurgy - an overview | ScienceDirect Topics
7.6.1 Pyrometallurgical Process. Pyrometallurgical processes have been used to retrieve PMs over the past 2 decades, as well as for removal and recovery of heavy metals. This procedure involves the incineration of wastes, followed by smelting in a blast furnace, drossing, melting, sintering, and reactions in gaseous forms at elevated temperatures.
pyrometallurgical process for production of chrome
Process Description Based on laboratory data derived from this investigation and on published data sources, as discussed previously in this report, it is proposed that chromium and other critical metals be recovered from superalloy scrap using a pyrometallurgical batch process comprised of the following steps: scrap melting; oxidation of ...

Ilmenite smelting: the basics T - SAIMM
Ilmenite smelting: the basics Constraints in ilmenite smelting Several constraints limit the operating ranges of ilmenite smelters. One of the major constraints is on the slag composition. The reason for this is that the chlorination process can handle only low levels of impurities (Table I), mainly because of the effect of impurities such as ...
