Tailings - Mt Todd Gold Mine

This type of recovery technique is commonly used throughout the world. Following the recovery of the precious metals, the pulp (a mixture of finely ground ore and water) will be thickened to recover part of the water containing the cyanide. The processing plant will produce tailings as a slurry at a density at about 55% solids and 45% water.

Recovery of gold from the Mouteh Gold Mine T tailings

2009-12-4  Recovery of gold from the Mouteh Gold Mine tailings dam of samples taken was around 200 kg (5–7 kg from each hole). The gold assay of the samples ranged from 0.6 to 2.3 g/t, with an average of 0.976 g/t (1 g/t). It was observed that the gold assay increases from the bottom to the top of the holes, indicating that the plant used to perform better at the

New approaches for extracting and recovering metals

2017-5-15  However, mine tailings may also be recycled and reused, e.g. manganese-rich tailings could be used in agro-forestry, building and construction materials, coatings, cast resin products, glass, ceramics, and glazes (Lottermoser, 2011). Increasing demands for metals, coupled with depleting reserves of high-grade primary ores, has meant that waste materials from historic mining operations
