ABSTRACT:
The potential K.sub.2 O content of cement clinker due to the presence of potassium compounds in the raw feed mix is substantially eliminated by introducing an active agent into the kiln along with or in conjunction with the fuel used to fire the kiln. The active agent is effective to convert K.sub.2 O to KCl and preferably is a chlorinated organic waste product burned along with the fuel.
