'''Pyroprocessing''' (from [[Ancient Greek|Greek]] Πυρος = ''fire'') is a process in which materials are subjected to high temperatures (typically over 800°C) in order to bring about a chemical or physical change. Pyroprocessing includes such terms as [[roasting (metallurgy)|ore-roasting]], [[calcination]] and [[sintering]]. Equipment for pyroprocessing includes [[kiln]]s, [[electric arc furnace]]s and [[reverberatory furnace]]s.

Cement manufacuring is a very common example of pyroprocessing. The raw material mix ([[raw meal]]) is fed to a kiln where pyroprocessing takes place. As with most industries, pyroprocessing is the most-energy intensive part of the industrial process.

Pyroprocessing is usually the most energy-intensive stage of an industrial process.
