Recycling of Mine Wastes in the Concrete Industry: A Review

The mining industry generates a substantial amount of waste materials, including tailings and waste rocks, which, if not managed correctly, pose threats to the environment and public health due to their long-term accumulation and disposal. Simultaneously, the construction sector consumes important amounts of natural resources like water and rocks. However, research shows that inert mining waste can serve as a substitute for conventional raw materials in construction, particularly in concrete. This review focuses on using mining waste as an alternative to concrete technology to promote cleaner practices in construction and circular economy in mining. Mining waste, with its physical characteristics and chemical composition, can function as diverse components in concrete, such as sand, aggregates, and binders. This article assesses these properties and explores their incorporation into concrete production, aiming to stimulate further research and development, foster environmentally responsible approaches, and underline the direct link to reaching SDGs to achieve sustainability in the construction industry.
