The Cement Manufacturing Process - Advancing Mining

The Cement Manufacturing Process By Darrell Leetham 08.20.2015 Different minerals need to be mined in order to make cement. Limestone (containing the mineral calcite), clay, and gypsum make up most of it. The US Geological Survey notes that cement raw materials, especially limestone, are geologically widespread and (luckily) abundant.
