Stage of Cement Manufacture. There are six main stages of cement manufacturing process. Stage 1 Raw Material Extraction/Quarry. The raw cement ingredients needed for cement production are limestone (calcium), sand and clay (silicon, aluminum, iron), shale, fly ash, mill scale and bauxite. The ore rocks are quarried and crushed to smaller pieces of about 6 inches.
Manufacturing can be by either the wet or dry process. This is an aerial viev/ of the General Portland Cement Company wet process plant located near Miami in Dade County, Florida. The appear ance of a dry process plant from this view would be essentially the same.
Sep 16, 2019· A variation of this process can be used to convert calcium carbonate (CaCO 3) into calcium hydroxide (Ca(OH) 2), which can then be used to make Portland cement without producing any greenhouse gas emissions. Cement production currently causes 8 percent of global carbon emissions.
