Water recycling and tailings management equipment can help aggregate producers recover process water from the waste stream for reuse in the wash plant, which is beneficial in areas where water is scarce or expensive to buy.
Tailings ponds are massive earth structures used to store coarse and fine solids contained in the oil sands deposit and recover water back to the main processing plant. These ponds are temporary storage facilities and need to be reclaimed when no longer in use.Fine solids from tailings streams tend to trap large volumes of water, …
Tailings pond is a place that is used to store metallic/non-metallic tailings or other industrial wastes and to clarify tailings water. Main functions of tailings pond: safe and rational storage of tailings, environmental protection, conservation of energy and water. A tailings pond usually consists of pond area, tailings dam, flood discharge ...

Settling ponds, also known as settling basins, decant ponds, or tailing ponds, are used for process water sedimentation. This process can be slow and requires a large site footprint. Mucking ponds and shutting down early to 'let it settle' kills production hours. ... Turnkey clarifiers connect with your sand and gravel wash plant, reducing ...
The key to unlocking this value is through a combination of washing, scrubbing and classification or by isolating those difficult to remove fractions using our modular tailings recovery systems. High value ore is recovered through separation of fine ore fractions from slurries or ponds, while coarse fractions are washed, scrubbed and separated ...
Traditionally, these tailings are sent to a settling pond or lagoon to separate the solids from the liquid in the waste stream. However, settling ponds can be time …
Aims Ecological restoration of mine tailing ponds plays a crucial role in managing heavy metal pollution and enhancing biodiversity. This study aimed to investigate the ecological restoration potential of pioneer plants under high manganese metal pollution, as well as the microbial community composition and functional characteristics of their …
The plant has been in operation since 2012 and annually process more than 1 million tons of ROM apatite ore to collect 350,000 tons of apatite concentrate to supply the fertilizer industry in Vietnam. After many years of operation in the plant tailing pond, a large volume of tailing has accumulated with content of 6–8% P 2 O 5. As …
Considerable amounts of coal particles are accumulated in the tailing dams of washing plants which can make serious environmental problems. Recovery of these particles from tailings has economically and environmentally several advantages. Maintaining natural resources and reducing discharges to the dams are the most …
The reclaim pond(s) (or return pond(s)) store the water that is being decanted from the TMF. Reclaim ponds are sometimes referred to as decant ponds which in most parts of the world is another name for the supernatant pond. A reclaim pond is situated outside the confining walls of the tailings storage area a short distance away (figure 7).
Tailings pond Refers to the water stored on-site to wash ore and receive waste tailings as a residue. This provides both a water supply and a sediment trap. Two serious environmental problems ensue. The water leaches out metals and other dangerous elements that were formerly trapped underground in a reducing (non-oxidizing) environment ; acidic wastes …
Tailing, geophysical logging, correlation, spatial distribution, heavy mineral, ... The flow of the washing process starts from the water in the pond being pumped to the washing plant, the washing wastes are channeled into the sediment pond, then the recycling process is carried out through closed circulation by being channeled back into the ...
Tailing, in context to mining, is defined as the waste or non-economic by-product generated during mining activities, processing of minerals, and other materials that contain small amounts of residual valuable minerals, chemicals, water, and heavy metals (Adiansyah et al. 2015).Studies indicated that the process of mineral exploitation and …
The breach of a tailings pond at the Mount Polley copper and gold mine in B.C. has released 10 billion litres of mining wastewater into local waterways in early August.
Once the tailings accumulated in the pond, the plant had to be shut down for the pond to be cleaned out and made operational again. ... The recycled water is available immediately for reuse in the wash plant, and thanks to Rich Voss' creativity, the filter cake is also sold as washed levy fill.

Learn what tailing ponds are, how they are used in mining operations, and what risks and impacts they pose. Discover how precision measurement instrumentation can improve tailing pond management …
The pond materials contain large amounts of Fe-oxyhydroxides, sulphates, and heavy metals (Cd, Cu, Pb, Zn) mainly Pb and Zn. Since the physicochemical conditions are not suitable for plants, tailing ponds are devoid of vegetation, but in the surroundings, it is possible to find a high biodiversity.
2023), becoming pioneer plants in the restoration of vegetation in tailing ponds. These plants facilitate the creation of a conducive environment for the survival of diverse microorganisms within the rhizosphere and engage in interactions such as competition and coopera-tion between plants and microorganisms (Chepsergon and Moleleki 2023).
The treatment plant is currently in a "safe standby" condition. Active remediation continues on an interim basis, through conveyance of extracted groundwater directly to the solar evaporation pond. In this process, clean water evaporates to the atmosphere and contaminants are safely accumulated in the pond in dissolved form.
