The ratio of tailings to concentrate is commonly very high, generally around 200:1 (Lottermoser, 2007).Moreover, as the point of peak metal production is surpassed, the extraction of lower grade ore is an established long-term trend (Mason et al., 2010).For example, in Australia the average Cu grade was c. 10% in 1885 but it fell to 1% by 2005, whereas in Canada the average Ni grade was c. 5% ...

galena table tailing - aurorasulmare.it

The pH of the Nacozari mine tailings ranges from 3.7 to 4.2 and so this process would be expected to occur (Table 1). This can be contrasted to carbonate-rich tailings that might be found in arid environments, where the acidity produced by sulfide oxidation is neutralized and pH values are near neutral (e.g. Blowes et al., 1998 ).

chalcopyrite tailing sampling

These tailings are rich in sulphide minerals particularly pyrite and chalcopyrite. Oxidation of these minerals produces the wellknown problem of acid mine drainage. In this research, a depth sampling was conducted over the tailings materials. Two vertical trenches (A and B) were excavated in tailings from the surface to a depth of m. Read More

Jan 08, 2018· The Brunite tailings are characterized by a typically grey-colored sandy texture. The uppermost first meter corresponds to red-colored tailings resulting from oxidizing surficial processes. At depths of 5 to 11 m and 20 to 23 m, the mine tailings turn to a clayish texture and show higher contents of galena and sphalerite.

Spain has a long mining tradition dating from pre-historic times up to the present day. The cessation of mining activity has generated a large amount of mine wastes, most of which represent geochemical hazards. Mine tailings are watery sludge composed of medium-to-fine-grained material, resulting from grinding and mineral processing (e.g., galena, pyrite, sphalerite, and arsenopyrite).
