Pyrometallurgy

Chemical reactions, changes in state, and simple temperature changes

Converts carbonate ores to oxides

Mechanisms of heat transfer (conduction, convection, radiation)

Separation by melting

It is an example of roasting (check multiple answers)

Physical and chemical changes, stability of phases in certain conditions

Measurement of temperatures

Heating of ore material with binder to convert fine particles to larger lumps

Requires heat to accelerate chemical reactions and melt the metallic and non-metallic

Its method has been predominant abundance and lower cost of fossil fuels
