Dry Stack Tailings AirDried as an Alternative to

This proposition is not a solution for every site. However, as the following case study illustrates, airdrying of paste or thickened tails can be a viable option for dry stacking and an alternative to filtered tailings. Dry Stacking With Relocation in Mind. First, lets define the term dry stacking.

Rise rate parametrizes the area required to recover the design flow or solids loading, the design dry tonnage. In high rate thickener (HRT) designs the rise rate or solids loading will dictate the required tank diameter for any given throughput.

TECHNOLOGY FACT SHEETS FOR EFFLUENT TREATMENT

The gravity thickening design is similar to a clarifier. Thickeners are usually circularshaped; the feed is carried out through a pipe to a central hood serving as distribution and still area, with a height that has no effect on compaction or compression bottom area. Except for small thickeners, static and with hopper floo r, these units have

Challenger Mill Expansion and Tails thickener Como

The Challenger Expansion project involved the upgrade of the existing plant to increase production from 45tph to 64tph design throughput. This involved the refurbishment, relocation and installation of 850kW regrind mill from Mt Gibson WA to Challenger site complete with new mill foundations and addition of a secondary mill control room.

Figure 2. Thickener plant flow sheet. Reducing operational variability through control system improvements. Despite the design of the thickener and installation of good instrumentation, poor overall plant design, inadequate automation, or low operator focus can be contributing factors in thickeners that fail to consistently achieve the best

Tailings

Tailings are also called mine dumps, culm dumps, slimes, tails, refuse, leach residue, slickens, or terracone (terrikon). Examples Sulfide minerals. The effluent from the tailings from the mining of sulfidic minerals has been described as quot;the largest environmental liability of the mining industryquot;.

Developing MudMax for Paste Thickener BedLevel Measurement

Aug 23, 20190183;32;The interactions of these parameters are at the heart of thickener models. Knowing the bed depth is critical to maintaining stable thickener operation. Numerous methods have been employed to achieve reliable bedlevel measurement, including bed pressure, ultrasonic, capacitance, nuclear, vibrating probes, divers, and floats (to name just a few).

Evolute feedwell upgrade Carpentaria Gold tails thickener

Operation of slurry thickeners is generally a compromise between clean overflow water and underflow density. Either the 22m tails thickener will achieve a high underflow density which enables maximum water and cyanide recovery. Or it operates to improve overflow water clarity enabling a positive impact on gravity gold recovery.

Thickeners or thickener plants Outotec

Advances in thickener design have improved the degree of separation possible from tailings streams, however limiting the selection criteria to just the thickener can constrain the operation potential. Integrating ancillaries, automation and operator training with the equipment can improve operational outcomes and decrease operating costs.
