In pyroprocessing industries such as lime, calcined bauxite, refractories or cement manufacture, the loss on ignition of the raw material is roughly equivalent to the loss in mass that it will undergo in a kiln. Similarly, for minerals, the loss on ignition represents the actual material lost during smelting or refining in a furnace or smelter.

In some cases these oxides can all be found in the appropriate proportions in a single second raw material and cement clinker can be produced from a simple two component mix. Because of the inherent variability of naturally won raw materials however, the ability to control all of the chemical requirements with two components is limited.

In practice, the mixing of raw materials is never perfect and there are always regions within the clinker where the LSF is locally a little above, or a little below, the target for the clinker as a whole. This means that there is almost always some residual free lime, even where the LSF is considerably below 1.0.
