This research aimed at defining a route for recovering precious metals from a very heterogeneous gold bearing sulphide and arsenide concentrate that was partially roasted and dumped by the 1960s when Santo Ant243;nio mine closed. Gold occurs in this concentrate as free particles in the range of 10 100
Tailings, also called mine dumps, culm dumps, slimes, tails, refuse, leach residue, slickens, or terra cone (terrikon), are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore.Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining
As gold mining is an expensive exercise, opportunities for low cost gold production need to be found, which is spurring the retreatment of tailings, says State owned Minteks Minerals Processing
diversion drains above both tailings ponds intercept clean surface runoff from the adjacent hill and direct it to nearby streams to reduce the amount of water entering the tailings pond; the tailings storage facilities are surrounded by perimeter roads, and a perimeter drain.

The mine tailings are high on the list of tailings piles for North Carolinas Minerals Research Laboratory (MRL) to investigate in coming years for the potential recovery of fluorite, quartz, sulfides including silver ore minerals, and wolframite from the tailings pile, estimated to have at least 3 million tons. Commodity Review Industrial
These include residues from metal production (as shown in Fig. 1) phosphogypsum, bauxite residue (red mud), mine tailings, metallurgical slags and industrial process residues from thermal treatment facilities (coal ash, incinerator ash). Likewise, it is investigated if waste water streams may be a source of rare earths as well.
