Abstract: A method of making ferro-lime wherein fine iron containing particles are injected onto the surface of the lime in a kiln, between the discharge end of the kiln and the flame and while the lime is at a high temperature to react instantaneously with the iron in the fines thereby to produce ferro-lime. Also disclosed is a method of recovering the fines from ferro-lime production wherein ferro lime fines are injected into the kiln onto the surface of the lime between the discharge end of the kiln and the flame and while the lime is approximately at said temperature, thereby to agglomerate the fines onto the lime or ferro-lime product.

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.
