pdf methods for the disposal and storage of mine tailings

The processing plant will produce tailings as a slurry at a density at about 55% solids and 45% water. The thickened pulp, or tailings, will then be treated to destroy the remaining cyanide prior to the tailings leaving the processing plant. The tailings will be pumped to the tailings storage facility which will consist of an engineered earth ...

tailingsinfo tailings handling

Nov 18, 2019 The foremost benefit of dewatering tailings is the reduction of water that needs to be transported from a process plant to a tailings storage facility (TSF). Reduced water content means tailings slurry volume is decreased, allowing for smaller pipelines and pumping equipment to be used.

technical report design and evaluation of tailings

Where tailings slurry is deposited in the facility, the water separates from the heavier sand and silt particles and collects to form a decant/reclaim pond on the surface of the impoundment. The tailings pond water is then recycled back into the milling process for reuse. The tailings are contained within the facility

Tailings are fine and relatively uniform rock particles mixed with water to form a semi-liquid slurry. They are deposited in Tailings Storage Facilities (TSF) for management and storage. In some cases, tailings are dewatered to produce thickened tailings, paste tailings or filtered tailings (in decreasing degree of water content). See Appendix ...

Tailings Storage Management Generation of Tailings Fortescues iron ore processing facilities generate a fine-grained by-product, referred to as tailings. This material is pumped as a slurry via pipelines to specifically designed TSFs. Over time the fine-grained material settles, allowing water to be recovered and recycled.

A typical hydraulic slurry from a base metals mining operation is generated from cyclone underflow (same fraction used in underground sandfill or raising tailings dams). A paste system incorporates the full plant stream making use of the full PSD to impart various characteristics to

mining mine waste for technology metals metal tech news

Dec 19, 2017 Pumping, or slurry transport, is the link between thickening and the tailings storage facility, and this function is often the rate-limiting variable in a tailings system. Higher densities increase the pumping pressure required or limit the flow of gravity systems and can require expensive infrastructure to operate at higher water recoveries.
