Operation of gravel and sand pits and mining of clay and kaolin

NACE v2.1 Code: B08.12

About operation of gravel and sand pits and mining of clay and kaolin

NACE code 08.12 covers the operation of gravel and sand pits, as well as the mining of clays and kaolin. This industry plays a crucial role in the construction and manufacturing sectors, providing essential raw materials for a wide range of applications. The extraction and processing of these natural resources are vital to the broader economy, supporting infrastructure development, industrial production, and various other economic activities.

Production process

The main production techniques in this industry involve the extraction of gravel, sand, clays, and kaolin from natural deposits. This is typically done through open-pit mining or quarrying methods, where the materials are dug out from the earth's surface. The extracted materials are then processed, which may include crushing, screening, washing, and sorting to meet specific size and quality requirements.

Production inputs

The key inputs for this industry include the natural deposits of gravel, sand, clays, and kaolin. Additionally, the industry relies on heavy machinery, such as excavators, loaders, and crushers, to facilitate the extraction and processing of these raw materials. Energy sources, such as fuel for the machinery, and water for washing and processing the materials, are also important inputs.

Production outputs

The primary outputs of this industry are the processed gravel, sand, clays, and kaolin, which are then used as inputs for a variety of other industries. The gravel and sand are commonly used in the construction industry for the production of concrete, asphalt, and other building materials. The clays and kaolin are often used in the manufacturing of ceramics, paper, and various chemical products. Other NACE codes that may consume the outputs of this industry include 23.20 Manufacture of refractory products, 23.32 Manufacture of bricks, tiles and construction products, in baked clay, and 17.11 Manufacture of pulp, among others.
