Tailings Dry Stacking, A New Tailings Processing

2020-11-5  Process Flow of Tailings Dry Stacking In general, the tailings dry stacking technology is mainly composed of slurry pump, hydrocyclone, efficient improved thickener, high-frequency dewatering screen, chamber filter press and slurry conveying device.

Tailings Solutions for the Future Weir Group

2019-7-3  Dewatering involves removing liquid from waste slurry so that the remaining solids can be deposited in a tailings storage facility or returned to the site from which it was mined as backfill. There are several dewatering methods to render waste slurry to differing degrees of dryness, ready for transport from the plant to the deposition site.

2021-1-4  For this website the term tailings refers to the slurry waste output from the processing plant. The properties of tailings are dependent on the ore body being mined, the grinding and processing circuits, the reagent properties and the thickening process prior to disposal. For mines with similar operating parameters the tailings properties can still vary as processing plants never operate

A conceptual cost comparison of alternative tailings

For the slurry TSF design, as tailings deposition ceases, the facility will be left drying for a period of three years so the surface of the TSF will be trafficable for construction equipment to perform rehabilitation work. This involves hauling and placing a layer of hard rock on the top and side slopes of the TSF, capping with topsoil, and deep ripping and spreading of seeds for the revegetation of all disturbed areas. After an assumed three years for regulator approval of the rehabilitation

Tailing Disposal an overview ScienceDirect Topics

The predominant method of tailings disposal is by pumping and sub-aerial deposition of an aqueous slurry (typically at 30–45% initial solids concentration by mass and an initial gravimetric moisture content, w, of 233–122%) to a surface TSF. The tailings may be discharged from a single pipe outlet or from a number of reduced diameter spigots off the main perimeter pipeline.

MANAGEMENT OF TAILINGS: PAST, PRESENT AND FUTURE

2020-9-8  Conventional sub-aerial tailings slurry disposal to a surface tailings storage involves the processes of beaching, hydraulic sorting of particles down the beach according to their particle size and specific gravity, settling of particles, consolidation, desiccation if exposed to the sun and wind, and loading by an upstream raise or cover placed for rehabilitation purposes. Beaching and hydraulic sorting are best assessed on the beach. Settling involves very large deformation and little strength gain, consolidation involves large deformation and significant strength gain, and desiccation involves some deformation and substantial strength gain. Loading the tailings

Converting Tailings Dumps into Mineral Resources

2021-7-3  A number of developments in mineral processing technology have combined to make the retreatment of numerous tailings dumps a profitable proposition. This is particularly the case for tailings dumps created from the processing of platinum group elements (PGEs) from the UG2 reef in the Bushveld Complex (BC) of South Africa, which are now being retreated to recover chrome.
