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.. The excavated …
The most famous and successful industrial process for supercritical CO2 extraction is the coffee decaffeination process. It can also be used to extract any botanical oil from any plant material. There are many other essential oil extracts that are used in the supplements industry that utilize this process. Hops is a good example.
