Metal recovery from old tailings

Jan 23, 2015Conversion of sulfides into marketable selective concentrates is carried out in two stages: sulfide product is extracted from tailings, first, and processed, second, jointly with current ore material, using the accepted technology, or separately, by jet flotation. Sulfides are extracted from tailings using a channel-type hydroseparator.

Tailings

The amount of tailings can be large, ranging from 90–98% for some copper ores to 20–50% of the other (less valuable) minerals. Tailings, also called mine dumps, culm dumps, slimes, tails, refuse, leach residue or slickens, terra-cone (terrikon), are the materials left over after the process of separating the valuable fraction from the uneconomic fraction ( gangue) of an ore.
