Aggregates in mining refer to a broad category of coarse-to-medium-grained particulate materials used in construction. These include materials like sand, gravel, crushed stone, and recycled concrete.
Aggregates are essential components in the production of concrete and asphalt, playing a critical role in providing the necessary bulk, strength, and stability to these construction materials. They are sourced through various mining processes, including quarrying and dredging, and are classified based on size, composition, and intended use. The mining and processing of aggregates typically involve stages such as extraction, crushing, screening, washing, and grading.
In summary, aggregates are key materials mined for use in the construction industry, contributing to the foundational structure of infrastructure projects.
