Gypsum; anhydrite; limestone flux; limestone and other calcareous stone, of a kind used for the manufacture of lime or cement

cpc code 1520 covers a range of mineral materials that are essential for the production of lime and cement, two of the most widely used construction materials globally. These materials play a crucial role in the construction industry, supporting infrastructure development, building construction, and a wide array of other applications. The extraction and processing of these resources are vital economic activities, contributing to the overall growth and development of many countries.

The production of the materials covered under cpc code 1520 typically involves mining and quarrying operations. Gypsum, anhydrite, and limestone are extracted from natural deposits using heavy machinery and techniques such as blasting, crushing, and screening. The extracted materials are then processed, often through further crushing, grinding, and sorting, to meet the specific requirements for the manufacture of lime and cement.

The main inputs required for the production of the materials under cpc code 1520 include the natural mineral resources themselves, as well as various types of mining and processing equipment, such as excavators, crushers, and conveyor systems. Energy sources, such as electricity or fuel, are also essential for powering the extraction and processing operations. Additionally, labor, transportation, and infrastructure, such as roads and railways, are necessary to support the production and distribution of these materials.

The primary outputs of the industries covered under cpc code 1520 are gypsum, anhydrite, limestone flux, and other calcareous stones. These materials are then consumed by the 3741 Manufacture of cement, lime and plaster industry, which uses them as key raw materials in the production of cement, lime, and plaster. The outputs of cpc code 1520 also find applications in other industries, such as 1542 Manufacture of other chemical products n.e.c. and 5233 Wholesale of construction materials, hardware, plumbing and heating equipment and supplies.
