the tailings may heave to up to approximately 5 m. The 'mud wave' may reach its peak at approximately 20–30 m away from the toe of the rockfill, then diminishing gradually beyond this distance. 2.1.2 End-dumping method Figure 7 shows the model of the end-dump method. In this method, the dump face advances forward once

The predominant method of tailings disposal is by pumping and sub-aerial deposition of an aqueous slurry (typically at 30–45% initial solids concentration by mass and an initial gravimetric moisture content, w, of 233–122%) to a surface TSF.

 · tailings in impoundments or free-standing piles, backfilling underground mine workings and open-pits, subaqueous disposal, and the most common method, the disposal of tailings slurry in impoundments. Modern tailings impoundments are engineered structures for permanently disposing of the fine-grained waste from mining and milling operations.

 · Tailings landforms are an enduring legacy of many mining landscapes – the design and construction of these facilities to perform well for the next millennium is just as great a challenge and effort as is maintaining operational dam safety. This chapter provides an overview of leading practices for design, construction, deposition, stabilisation,

Tailings are a by-product of mining. After ore containing an economically-recoverable commodity is mined from the earth, that commodity is extracted in a processing plant or mill. After the commodity of value is extracted from the ore material, the resultant waste stream is termed "tailings". Typically, mill tailings range from sand to silt ...
