Cement cement extraction and processing: raw materials employed in the manufacture of cement are extracted by quarrying in the case of hard rocks such as limestones, slates, and some shales, with the aid of blasting when necessary. some deposits are mined by underground methods. softer rocks such as chalk and clay can be dug directly by excavators.

Cement, How It Is Produced Mine

Cement plants are typically located central to the minerals required to make the cement, which saves the transportation costs and reduces the price of the cement. once the ore material to be used for cement has been mined, it is transported to the crushingscreening plant, where it is crushed and screened, to produce the desired particle size.

Cement production is one of the largest industries in the world. annual world production in 2013 was approximately 4 gt (of which, about half was in china). it is produced in kilns at around 1400o c (2500 o f), and approximately 750 kg (1650 lb) of co 2 are released for each tonne (2205 lb.) that is made.
