ABSTRACT:
A method of making ferro-lime in a rotary lime kiln by feeding pellets containing iron into the kiln together with the stone to be processed. The pellets should be substantially dust free and strong enough to withstand the tumbling action of the kiln without disintegrating, and should be of a size and density compatible with the stone being fed to ensure proper mixing within the kiln. This invention is particularly adapted to the formation of ferro-lime or dolomitic ferro-lime.
