Pyrometallurgy is a branch of extractive metallurgy.It consists of the thermal treatment of minerals and metallurgical ores and concentrates to bring about physical and chemical transformations in the materials to enable recovery of valuable metals. Pyrometallurgical treatment may produce products able to be sold such as pure metals, or intermediate compounds or alloys, suitable as feed for ...
The efficiency of the recovery phase depends on both temperature conditions and the composition slag, and introduced additions. The exploration of the possibility and feasibility of the liquid-phase restoration for steelmaking waste slag of the Zlatoust Metallurgical Plant applying the induction heat installation is the aim of this study.
Dec 09, 2019· Furnace classification by heat source – Heat is generated in the furnace to increase the furnace temperature to a level which is higher than the temperature needed for the process, either (i) by the combustion of a fuel, or (ii) by conversion of electric energy to heat. Some furnaces also utilize the waste heat from the metallurgical process.
