Stone, sand and clay
CPC v2.1 Code: 15
About stone, sand and clay
cpc code 15, 'Stone, sand and clay', encompasses a diverse range of industries that extract and process various types of natural mineral resources. These materials are essential for construction, manufacturing, and a wide array of other economic activities, making this sector a crucial component of the broader economy. From the production of building materials to the extraction of specialized industrial minerals, the industries within this code play a vital role in supporting infrastructure development, industrial processes, and economic growth.
Production process
The production techniques used in the stone, sand, and clay industries vary depending on the specific material being extracted and processed. Generally, the process involves mining or quarrying the raw materials, followed by various stages of crushing, screening, washing, and sorting to produce the desired product specifications. Advanced techniques such as flotation, magnetic separation, and chemical processing may also be employed to refine and purify certain mineral resources.
Production inputs
The main inputs required for the stone, sand, and clay industries include the natural mineral resources themselves, as well as specialized mining and processing equipment, energy sources, and transportation infrastructure. Depending on the specific application, additional inputs such as water, chemicals, and fuel may also be necessary. The availability and quality of these raw materials and supporting resources can significantly impact the productivity and competitiveness of the industries within this cpc code.
Production outputs
The industries within cpc code 15 produce a wide range of outputs, including 16 Manufacture of glass and glass products, 23 Manufacture of other non-metallic mineral products, and 41 Construction of buildings. These materials are essential for the construction, manufacturing, and industrial sectors, as well as for various consumer and commercial applications. The specific outputs can range from aggregates and building stones to specialized industrial minerals and advanced ceramic products.
