There are three main stages in the cement production process. The first stage is the preparation of raw materials, such as limestone, clays, shale and iron ore that are mined and crushed, as necessary. The crushed raw materials are mixed in different proportions to obtain the desired composition of the feed to the cement production process.

The Manufacture of Portland Cement nzic.org.nz

The cement manufacturing process involves four distinct stages, and these are outlined below. Step 1 Quarrying The raw material for cement manufacture is a rock mixture which is about 80% limestone (which is rich in CaCO3) and 20% clay or shale (a source of silica, alumina and Fe2O3). These are quarried and stored separately.
