Abstract

A process is disclosed for the manufacture of cement clinker. The process includes providing a first material providing a metal M or an oxide thereof, heating the first material in a furnace to form a first heated material; and contacting a surface of the first heated material with a second material providing at least CaO, Ca(OH)2, or a mixture of CaO and Ca(OH)2 to form a slag. The heat from the first heated material promotes clinkering of the slag to form a cement clinker.
