Tailings Overview Harvey McLeod October 2013
Tailings Reduce Hydraulic Gradients and make a Safer Dam •Grouting of core zone foundations normally eliminated. •Width of core zone can be reduced to reflect lower gradients •Risk of "piping" failure is lower than for a water dam. •Hydraulic fractures – "selfhealed" with tailings Highland Valley Copper
What Are Tailings?
Tailings consist of ground rock and process effluents that are generated in a mine processing plant. Mechanical and chemical processes are used to extract the desired product from the run of the mine ore and produce a waste stream known as tailings. This process of product extraction is never 100% efficient, nor is it possible to reclaim all ...
MINING RECLAMATION IN NORTH AMERICA
A Biosolids Success Story Large quantities of mine tailings were placed in a tailings impoundment in a drainage area, known as the Robinson Tailings Pond, adjacent to the Climax mine. Reclaiming and revegetating the mine's historic tailings has been no small feat. Mining reclamation here is affected by a challenging climate

· Despite successful liberation of the molybdenite entering this circuit, ultrafine losses were noted in the circuit tailings, or copper concentrate. It is believed that this is caused by the open circuit format of the regrind circuit, which would typically produce excessive ultrafine. 2.
Tailings
Terminology. Tailings are also called mine dumps, culm dumps, slimes, tails, refuse, leach residue, slickens, or terracone (terrikon).. Examples Sulfide minerals. The effluent from the tailings from the mining of sulfidic minerals has been described as "the largest environmental liability of the mining industry". These tailings contain large amounts of pyrite (FeS 2) and Iron(II) sulfide (FeS ...
Tailings
Tailings are Mine Waste. Tailings are the waste materials left after the target mineral is extracted from ore. They consist of: Trace quantities of metals such as copper, mercury, cadmium, zinc, etc. Additives used in processing, such as petroleum byproducts, sulfuric acid and cyanide.
Review, Evolution and Optimization of the Kansanshi Mixed ...
When floating the flotation tails in the laboratory without any additional reagents, the recovery was seen to improve by an average of 5% while floating the tails with additional reagents improvements of up to 10% were observed (Figure 1). The higher the acidsoluble copper (AsCu) feed grade, the higher the observed improvement (Figure 2).
