Recycling coal combustion by-products for minesite rehabilitation

Mehdi Azadi

The rehabilitation and closure foaminess often impeded bythepresence ofminewastes(spoils, rejects, tailings) with undesirable chemical and physical properties that increase the risks of acid and metalliferous drainage, spontaneous combustion, salinity, dust generation, and erosion. At the same time, the various types of coal combustion byproducts from power stations have unique chemical and physical properties such as an alkaline nature, pozzolanic binding effects, high water holding capacity, and particle size distributions which can be beneficial for mine rehabilitation.
