With an estimated 3,500 tailings storage facilities around the world, the need for effective tailings water management is clear and present. On average, 3 of these tailings dams fail each year with incidents over the last 15 years on the rise. ... Cost savings. Significantly reduce operational costs by minimising the need for off-site disposal ...
The invention relates to an electricity-saving and water-saving method for treating tailings. The electricity-saving and water-saving method for treating the tailings comprises the steps of concentrating a tailing to obtain a high-concentration tailing while fractioning a low-concentration tailing; discharging the high-concentration tailing to a tailing pond through a mortar pump; then ...
This section reviews these key water management considerations for conventional tailings storage as well as the infrastructure required to control ponded water. The intention of this section is to highlight how problematic …
Instead of being pumped to a tailings facility as a highly diluted slurry, the Ecotails system dewaters and filters tailings to result in a moisture content of just 10% to 25%. Up to 90% of the water in tailings can therefore be reused in the plant, rather than being lost to evaporation from a traditional tailings dam.
tailings (P&TT) technology. In the process a simple water consumption model was developed for estimating the overall water consumption of the mine. The model indicates that for the Mogalakwena tailings, significant water savings are achieved by discharging thickened tailing directly to the TSF but only at
However, the organic fraction within tailings PA water and tailings has not been well characterized throughout the literature. Laboratory studies often do not account for the variability among different tailings ponds spread across the AOSR, or the spatial variability within individual ponds ranging from 0.5 to 12 km 2. At the same time, the ...
Water savings, the cost of tailings and their reclamation are becoming increasingly significant for sustainable and economically viable mining for long-term survival. Today, about 70% of the mines operated by the major mining companies are in countries where water scarcity is a major risk for society. Therefore, responsible usage of water is ...
Unlike traditional wet tailings, where tailings are mixed with water and stored in ponds, dry stack tailings involve dewatering the tailings to remove excess moisture before stacking them in a controlled manner. This results in a stack of …
In mining, tailings are piped out of the mine as slurry—a mixture of water and finely crushed rock—and deposited into tailings dams. The slurry separates over time, with solids settling to the ...
The rheology analysis indicated that the coal mine tailings with 65–70% solids are not pumpable and these two options are beyond the scope of this study. The results of the analyses show that the optimal scheme process in terms of water saving, water management, and energy consumption involved tailings with 50% mass solids.
Many scholars have claimed that the dewatering of tailings can reduce the costs of the facility, increase the mineral recovery, and save water (Van Berkel, 2007, Boger, 2013, McPhail and Brent, 2007). Thickened tailing technology is advantageous when used for the saving of water in mines.
The invention provides a water saving process for dry emission of tailings. The process comprises the following steps of: concentrating the tailings and depositing the sand by an efficient cyclone, namely entering coarse particles into a ceramic filter to form dry emission and simultaneously perform overflowing, namely concentrating fine particles, and entering the bottom flow into a …
By significantly reducing water content, it reduces risk of dam failure and makes the tailings more resistant to seismic activity. Additionally, dry stacking enables continuous …
The invention discloses an energy-saving method for treating tailings. The method comprises the following steps: concentrating tailings, thereby obtaining high-concentration tailings and separating out low-concentration tailings, and directly discharging the high-concentration tailings to a tailings pond through a mortar pump; starting a power-saving and water-saving program, …
A mine water reduction model was introduced by Gunson and coauthors [1] to improve the mine water system performance in a copper mine plant by comparing scenarios of water reduction with the base scenario that does not consider water savings. Scenarios include tailings dewatering technologies, and water conservation options.
The application of tailings dewatering technologies for increasing tailings water recov-ery is a relevant step to reduce water losses (resource from freshwater or seawater supplies) caused …
Mines are looking for ways to save water and reduce the footprint of tailings facilities. Both can be achieved with FL's Ecotails tailings solution.
Excessive water can saturate the embankment, leading to liquefaction-induced flow of tailings. Dam failures can result in catastrophic consequences, including loss of life, …

Waste slurries that are often sent to a pond can be reclaimed, saving water for reuse, and allowing fines to be recovered and reprocessed. ... Tailings Management & Water Recycling Water recycling and tailings management is …
Note that a water saving of 14.33% corresponds to an increase in solid concentration from 30 to 45%; this was achieved without any change in pressure loss by adding 3.267% of DRA, which equates to 0.123 m 3 of water savings per 1 m 3 of tailings slurry. This study also found that the required polymer percentage to keep the same pressure loss ...
Save water and cost by dewatering tailings Tailings are still frequently stored in large settling basins or sludge ponds. They are a great burden on the environment. The process water bound by the tailings remains unused. With modern dewatering solutions, mining residues can be treated economically and the process water that they contain can be ...
