Alkali activation as new option for gold mine tailings

Jun 20, 2018· Table 2 presents the main elements of the raw materials and the physical properties of the mine tailings used. Mine tailings are fine-grained materials with a mean particle size of around 49 μm and consist mainly of SiO 2, Al 2 O 3, and CaO.In addition, a significant amount of iron, around 10%, and a high level of sulphur content were detected (), confirming the presence of the crystalline

Solidification/stabilization of gold mine tailings using

Dec 01, 2019· With a higher amount of mine tailings, the ettringite amount decreased, and the main phases of initial mine tailing powder still occurred. With higher amounts of mine tailings, there was no changes in the phase composition of the samples, which supports the observations of a poor consolidation of the matrix with too high content of mine tailings.

From Tailings to Treasure? Miners Make Advancing Mining

May 07, 2015· DRD Gold, one of the first South African companies to abandon traditional mining to focus on extracting gold from tailings. New technology allows it to recover up to 40% of the gold left in particle form in tailings. DRD Gold extracted 33,600 ounces of gold, worth nearly US$40 million, in the last quarter of 2013.
