From Tailings to Treasure? Miners Make Money Reprocessing

Mine sites typically manage tailings by constructing ponds secured by dams. According to the web site miningfacts, another strategy is to produce thickenedtailings, which are pressed or have chemicals added to remove excess water. Thickenedtailingscan be mixed with cement and used in construction or as backfill in underground mines.

Tailingsfo Conventional Impoundment Storage The

A conventional impoundment is a surface retaining structure designed to store both tailings and mine water, with the aim of reclaiming the water for use in the processing plant as required. There are principally two types of surface impoundments, a water retention type dam, and a raised embankment that has many configurations (Vick 1990).

Paste tailings is a modification to the conventional methods of disposal of tailings (pond storage). Conventional tailings slurries are composed of a low percent of solids and relatively high water content (normally ranging from 20% to 60% solids for most hard rock mining) and when deposited into the tailings pond the solids and liquids separate.

Mine tailings are reused for producing clay, tiles, glass, and concrete. Mine water is treated and then used for dust and particulate suppression, agricultural/industrial use, and as a coolant. Despite numerous recycling methods, the majority of mine waste is still stored in facilities or waste sites.

Surface TSFs are typically sized and operated in a way to minimise the initial capital cost of the facility, driven largely by the net present value approach to accounting. This generally leads to too small a storage, too fast a rate of rise of the tailings, and difficulties in managing supernatant water.
