The mining sector enters significantly in the cement industry, this sector is considered the most important in terms of extraction, mining, and processing of raw materials.

The production of cement is a two-step process that involves producing a clinker from raw materials (mainly limestone and clay) that is heated within a kiln at an intense heat, before being cooled at 100 o C – 200 o C. In a second step, gypsum and sometimes additions like coal fly ash are added to the clinker and ground to a fine cement powder.

Underground hard rock mining refers to various underground mining techniques used to excavate hard minerals, usually those containing metals such as ore containing gold, silver, iron, copper, zinc, nickel, tin and lead, but also involves using the same techniques for excavating ores of gems such as diamonds or rubies.

The Canadian company CarbonCure Technologies has developed a process that injects waste CO 2 into a typical concrete production process, effectively replacing a small amount of cement with CO 2 without compromising the concrete’s strength or integrity. Once in the mix, the CO 2 changes into calcium carbonate, the chemical equivalent of the limestone used in the production of conventional cement.
