Abstract It is the contention of this paper that there remains considerable confusion regarding the mechanisms and benefits of thickened tailings schemes. The terminology and interpretation of terms like thickened tailings and paste receive some consideration, in light of some observed contradiction in the industry.

Abstract Tailings transport is an integrated element in any wet tailings storage facility (TSF Tailings from the process plant are often thickened to a moderate or relatively high (but still pumpable) solids concentration, depending on several parameters mainly the TSF deposition requirements and strategies, process plant water security status and the dewatering technology utilised.

With thickened paste and filtered tailings, a finer grind can affect the payback of tailings disposal by increasing capex costs (e.g., lower settling rates and greater retention times requires a larger thickener) and increasing operating costs (e.g., higher flocculant, power and filter cloth consumption.

Jun 20, 2012· This paper reflects on whether or not the potential benefits attributed to paste and thickened tailings have been realised. Using a grading system, thirteen benefits ascribed to the technology some s ago are evaluated. Data are taken from case studies, and it is suggested that the key proven benefits are reduced operating costs in some

A thickened tailings or paste disposal area is designed to store solids and a little excess water. Recovery of process water is carried out in the thickener before deposition. Due to the higher beach slope, the footprint of the area needed is half the size of a conventional tailings pond.

Paste Thickening Optimizes Tailings Disposal and Water Recovery. Mine tailings disposal, and its impact on water usage, is an important concern for any mining company. The challenge today, whether extracting aluminum, zinc, g or iron ore, is how to dispose of tailings material such that it is contained and stable, while maximizing water

Paste and Thickened Tailings. The November edition of the Journal contains papers that were presented at Paste 2012, the 15th International Seminar on Paste and Thickened Tailings that was held in the Pilanesberg during April this .
