Recycling of mine tailings for the geopolymers production: A systematic review

The mining sector generates a considerable amount of waste stone and tailings, which constitute a rrsubstantial hazard to the ecology. The most prevalent method of disposing of these industrial rrwastes is by dumping, which adds to soil deterioration and water contamination and also takes up rrvaluable land. Fortunately, it can be recycled in a variety of ways, including the promising rrgeopolymerisation technique, which converts waste into value. This article discusses recent rradvances in the production of mine tailings-based geopolymers composites (MT-GPC) from waste and rrindustrial by-products as a potentially sustainable construction material. Besides, focusing on the rrfollowing rraspects: economic and production perspective; environmental consequences and waste rrdisposal; physical and chemical properties; mechanical properties; durability properties; rrmicrostructure propertiesr; thermal properties; and potential applications of MT-GPC.r
