A method for the production of cement clinker comprises the introduction of vitrified slag into the feedstock stream prior to the clinkering zone. The addition of vitrified slag can increase the clinker output rates and/or reduce the energy requirements for maintaining the kiln temperatures. In one embodiment, the vitrified slag is a vitrified blast furnace slag.
