The object is to deposit thickened tailings or a paste using the least amount of energy, while recycling the most water The costs for these systems vary, but the exorbitant cost of engineering and constructing a tailings impoundment usually makes the decision easy...
Jul 19, 2019 0183 32 Tailings management, perceived by many as simply a cost burden, is a key area potentially targeted for savings partner content Thickened tailings could be part of ,...
A thickened tailings or paste disposal area is designed to store solid and little excess water Recovery of process water is done in the thickener prior deposition Due to higher beach slope, the footprint of the area needed is half size compared with conventional tailings pond High viscosity in tailings and less water in the pond results in ....
May 01, 2015 0183 32 Yet today, less than 1 percent of iron ore mines employ systems for paste thickening, despite its benefits fortailings disposal optimization Nevertheless, mining projects in developed countries conform to stringent water conservation and environmental standards in tailings disposal, and developing nations too are instituting significant steps to require water reuse and mitigate ,...
Nov 06, 2017 0183 32 Project Classification Detailed Engineering, Thickened tailings disposal system Background To treat high grade ore Yanacocha implemented a milling process at the La Quinua operation However, limited sites were available for the tailings storage facility To best utilise the available area the tailings storage facility is fully contained ....
Tailings management, perceived by many as simply a cost burden, is a key area potentially targeted for savings partner content Thickened tailings could be part of the solution to safely ....
PDF The use of thickened tailings is becoming more and more common in a wide range of waste materials and in very different conditions Their behaviour is complex and affected by several factors...
tailings, already perceived by many as simply a cost to the mine, is one of the key areas targeted for savings With constraints on water availability and costs associated with water, particularly in arid environments, thickened tailings disposal becomes an attractive scenario...
Jun 07, 2019 0183 32 The successful implementation of filtered, paste and thickened tailings technology is dependent on a sound understanding of slurry colloidal behavior, thickening and thickener operation, filtration, rheology, pump and pipeline transport systems, conveyor transport and disposal ,...
Challenging economic conditions and increasingly strict environmental regulations demand tailings pipeline systems that travel longer distances, at higher concentrations and with longer design liv Our solutions include gravity flow, open channel flow, energy dissipation, multiple pumps in series, and thickened paste disposal...
Jun 16, 2017 0183 32 A typical concave-shaped, conventional paddock TSF could be transitioned to have a convex, thickened tailings surface towards the end of operations through modifying the tailings disposal strategy to create a water-shedding final landform, limiting the amount of surface re-shaping and borrow material required...
T1 - THICKENED SLURRY DISPOSAL METHOD FOR PROCESS TAILINGS AU - Palmer, Bertrand AU - Krizek, Raymond John PY - 1987/1/1 Y1 - 1987/1/1 N2 - Common practice in the disposal of process tailings consists of impounding the wastes as thin slurries or suspensions in ,...

It is Thickened Tailings Disposal Thickened Tailings Disposal listed as TTD Thickened Tailings Disposal - How is Thickened Tailings Disposal abbreviated? , Thickened Tailings Disposal thickened up Thickened Waste Activated Sludge thickenedly thickenedly thickener ....
The use of a thickener, without filtration, to produce a non-settling paste also called thickened tailings with non-Newtonian rheology has been practiced in Australia for many years for red mud disposal The application of paste thickening technology outside of alumina is relatively new...

Barry A Wills, James A Finch FRSC, FCIM, PEng, in Wills Mineral Processing Technology Eighth Edition , 2016 1625 Submarine Disposal For operations that are close to the sea, submarine tailings disposal is an alternative to conventional tailings disposal, provided the governmental regulations permit disposal in such a manner...
A conventional tailings pond is designed to store both the solid and the water from tailings Here, the solids segregate and settle, and process water is stored and recovered A thickened tailings or paste disposal area is designed to store solids and a little excess water Recovery of process water is carried out in the thickener before ....
The central thickened discharge system of tailings disposal takes advantage of the natural beach slope formed by sub-aerially discharged tailings, and the non-segregating properties of thickened tailings, to create a homogeneous conical stack The need for containing embankments can be largely avoided leading to capital and operating cost savings...

Download the white paper for a detailed comparison between thickened tailings disposal and conventional lean tailings disposal...
The grind to obtain a given recovery may impart additional costs for tailings disposal and mine backfill With thickened paste and filtered tailings, a finer grind can affect the payback of tailings disposal by increasing capex costs eg, lower settling rates and greater retention times requires a larger thickener and increasing operating ....
In situations where disposal space is limited, having a practical tailings- disposal option may mean the difference between being able to mine a promising ore body, or not Thickened tailings deposits can support loads more quickly than can other forms of disposal, so ,...
Abstract Musselwhite Mine in Northwestern Ontario, Canada began thickened tailings disposal in May 2010 Surface disposal of thickened tailings for the 4,000 tpd gold mine was chosen following a series of studies beginning in 2002 to investigate options to expand the capacity of the tailings ,...

----- Design and Evaluation of Tailings Dams DESIGN AND EVALUATION OF TAILINGS DAMS 1 INTRODUCTION In order to obtain the metals and other minerals needed for industrial processes, fertilizers, homes, cars, and other consumer products, large quantities of rock are mined, crushed, pulverized, and processed to recover metal and other mineral valu...
Aug 03, 2016 0183 32 Mine tailings disposal, and its impact on water usage, is an important concern for any mining company The challenge today, whether extracting aluminum, zinc, gold or iron ore, is how to dispose of tailings material such that it is contained and stable, while maximizing water reuse and minimizing surface footprint...
