Reprocessing Mine Tailings To Control Acid Rock Drainage

Extraction of cobalt from historic sulphide tailings

Mineralogical and geochemical characterisation of sulphide minerals in historic tailings can assist in determining whether there are economic and environmental benefits of reprocessing such materials using modern metallurgical practices. At the Old Tailings Dam (OTD), Savage River, Western Tasmania, 38 million tonnes of pyritic tailings were deposited (1967 to 1982), and

Mine tailings: reprocess, recover recycle

Reprocess tailings. Really? Yes, really. If the technology exists today to remove up to 90% of water from mine tailings and, if a mining company is going to make that investment anyway to secure its future operations, then frankly, it is irresponsible not to consider reprocessing the tailings that currently sit in its TSFs.

Increasingly stringent environmental regulations and industry adoption of waste minimization guidelines have thus, stimulated the need for the development of recycling and reuse options for metal related waste. This book, therefore, gives an overview of the waste generation, recycle and reuse along the mining, beneficiation, extraction, manufacturing and post-consumer value chain.
