Tailing Disposal - an overview | ScienceDirect Topics

On sub-aerial deposition, the tailings undergo hydraulic sorting down a delta that forms at a slope of between 1 in 50 and 1 in 150 (averaging about 1 in 100), settling and sedimentation, and self-weight consolidation. Hydraulic sorting of the tailings takes place due to particle size and G s differences. Some tailings, notably fly ash and some red mud, may undergo some cementation after placement.

PDF Project: [UOSE 034 and Understanding Oil Sands Tailings

1 What was the R&D gap and why was this project needed? The pressure conditions adopted here are quite low, which can be easily achieved in the real industrial tailings treatment. After treating 120 g MFT with 0.5 g BPEI and 0.5 g DFPEO, we could easily reclaim 30 wt% inbound water from the MFT.

Tailings Management - Environment | Suncor

Oil sands tailings are the remaining sand, water, clay, silt and residual hydrocarbons left after the majority of hydrocarbons are extracted from the ore during our extraction process. Tailings are managed at Suncor's Base Plant, as well as joint venture operations, Fort Hills and Syncrude.

Tailings Disposal Methods and Equipments | M&C

In the early days of the tailings dry discharge technology, full tail concentration-pressure filtration (filtration) is the main process.Although this process has obvious advantages over traditional tailings storage, a large number of problems have been found in the application process, including high one-time investment, high operating cost and large floor area.

Oil Sands Tailings Water Treatment Process Using Entrapped and

A biological process for treating oil sands tailings water containing naphthenic acids. The process consists of bioaugmentation followed by entrapment of bacterial cultures indigenous to oil sands tailings pond. Entrapped and bioaugmented indigenous cultures can be used in various types of

How to process tailings - Quora

In the tailings treatment of gold mines, filter presses are widely used. This method has the characteristics of low water content of filter cake and the filtrate can be returned to use. However, due to the low processing capacity of single machine, it is difficult to be used for

How mine tailings play the role in inorganic polymer research

The common way to activate precursors can be thermal treatment and mechanical treatment. In order to maximize the local availability and versatility, it is significant to develop the utilization of mine tailings especially in the section of sustainable construction materials 5 .

Process effluents and mine tailings: sources, effects and

12/19/2016 · Increasing population levels, growing economies, rapid urbanization and changes in consumption patterns have increased the demand for raw materials such as base and precious metals, leading to growing concerns regarding their availability and the global efficiency of the mine supply chain. Mine tailings, consisting of process effluents that are generated in a

Tailings Management : Renova Foundation

WHAT ARE TAILINGS? They are the residue of the material extracted in mining after treatment. After separating the metal of interest – which may be iron, copper, gold – the rest becomes tailings. In the region of Mariana, in Minas Gerais, it origins from a large number of iron particles that are mixed with the soil itself.

Mine Waste Transfer and Disposal Methods - Mine Tailings, Gangue

Tailings are finely ground rocks and other mineral waste as a result of mineral processing. Due to the way minerals are processed, tailings can contain concentrations of processing chemicals. This can make mine tailings an environmental concern, so proper transportation and disposal are crucial.

What you need to know about tailings ponds

There’s lots of research being done on treatment, but the water will always have to be treated. I don’t think there are any plans at all to make a tailings pond into a lake. It’ll always

Tailings - Paterson & Cooke

Tailings Slurry pipelines are commonly used to transfer mine residue from the processing plant to the tailings storage facility. Historically these pipelines were designed to operate at low solids concentrations, however as dewatering technology improved and solids concentrations increased, residue disposal systems have become significantly more complex. Designing an effective

TREATING CHROME TAILINGS FOR PGMs

Its operations are focused on the treatment of Samancor’s chrome tailings dumps on the Western and Eastern limbs of the Bushveld complex. The Samancor dump operations contain about 500,000 ounces of PGMs at an estimated average non JORC compliant grade of 2.6 g/t. Sylvania director Zoran Marinkovic explains that it is not economically viable to convert its resource to a JORC compliant

Oil sands tailings ponds are toxic. Canadian-made nanotech

Tailings ponds store water used in oil sands extraction, and contain a complex mixture of wastes that are toxic to vegetation and animals.

Oil Sands Operators Tackle Tailings Management Challenges

The tailings treatment setup also includes several 70-m-diam high-rate thickeners designed to dewater fine flotation tailings and to clarify and recover the warm process water for reuse in the extraction processes. The thickeners will produce underflow with a density of >50 wt% solids, along with overflow warm water containing less than 0.5 wt

Understand the basics of plasma treatment | What is Plasma?

Treatment with plasma remove foreign contaminants present on the surface of a material making it more suitable for further processing. Materials like plastics are prone to lose any type of printing or coating done on their surfaces because of their glossy texture unless treated.
