thickener in tailings recovery high popularity

Thickeners or thickener plants Outotec

Thickeners are recognized as one of the more cost-effective technologies for recovering water from tailings streams. Significant energy savings can be achieved by maximizing the recovery of water close to the mill. In addition, a higher density of tailings deposited in the dam tends to reduce the footprint and produce a more stable tailings deposit.

Tailings Paste Disposal More than Water Recovery

Water Recovery Paste thickeners thicken tailings to higher underflow solids concentrations than conventional and high-rate thickeners. For example, a tailings stream in an iron ore application could be thickened to 45-50% solids in conventional or high-rate thickeners. Conversely, the same tailings stream could be thickened to 65-70% solids

Tailings.info Thickened Tailings Storage A discussion

The potential for recovering high volumes of water at the plant (by the thickeners) eliminates the losses associated with the transport and storage of water either at the tailings facility or in holding ponds (Fourie 2003). Environmental problems such as seepage, spillage of process water and the potential for water to act as a transporter for tailings flows (e.g. embankment breach) is

Tailings.info Laboratory and Pilot Plant Testing Programmes

Pilot Thickening Trials: Limit Testing Onsite pilot thickener trials using a truck mounted or small scale thickener (typically up to 5 tonnes per day) operating for a short period of time, primarily to determine limitations of thickening an existing tailings feed. These styles of trials are driven by thickener vendors to adopt high rate, high compression or paste thickening technology.

Design Considerations for a Tailings Disposal System E &

T he drivers behind paste or high density thickeners are water recovery and cost savings with impoundment construction. Tailings impoundments have become a limiting factor for mines. In some parts of the world, permitting an expansion, let alone a new impoundment, is difficult. There are serious safety and environmental repercussions brought about by high runoff. By using paste or thickened

Thickening Resource Book

High Rate Thickeners High rate thickeners are designed specifically to maximise the flocculation efficiency of flocculants. They differ from conventional thickeners in feed well design, size and control. Unlike conventional thickeners, high rate thickeners must use flocculants. The basic design of a high rate thickener is below.

Recovering Cyanide From Gold Plant Tailings

and high overall gold recovery, it is . always necessary to add more cyanide during leaching than will be consumed in the leaching process. This excess cyanide reports to the tailings as uncomplexed or free cyanide, and it is often possible to recycle a portion of this cyanide at minimal cost. A number of gold plants around the world have adopted this approach. The basic requirements to
