The type of extraction method that can be used on mine waste depends on the mineral deposits the tailings come from and what processing approach was used to generate them, says Jowitt. If similarities are found between systems, similar approaches could be used across tailings facilities.
The overall closure design objective is to construct a facility (or facilities) that will sustainably retain the tailings at that site in perpetuity. Gold Fields TSFs incorporate closure objectives and expected outcomes, the final …
for high tailings facilities in the deep valleys of the Andes in South America. 2.1 NET PRESENT VALUE ACCOUNTING APPLIED TO TAILINGS MANAGEMENT There is a commonly held perception that transporting tailings as a slurry to a facility is the most economic approach. However, to a large extent this tailings dewatering, density and …
The study evaluated the tailings management practices across the gold leaching plants with respect to tailings storage and disposal, and found out that, 68.2% of the gold leaching plants dispose tailings on site as dry stacks, while 18.2% of the gold leaching plants dispose tailings off-site as dry stacks, with only 13.6% of the gold …
In the next decades many of the old tailings storage facilities (TSFs) could be re-processed if one considers the prices of metals, new uses of metals which today are not valuable, and the application of new, more efficient metallurgical technologies. In this context, in-pit disposal of mine tailings (IPDMT) is an attractive alternative to be used …
