Here are six categories of cement production that have potential for optimization. Raw Materials. The first step in the cement process is the recovery of the limestone and sometimes the extraction of clay. Online elemental analyzers can monitor material chemistry in real time, allowing for adjustments that will help extend the life of the quarry.
