How to generate value from tailings with reprocessing to ...

15/10/2019· Whether driven by regulatory compliances, tailings dam failure and water scarcity, mine tailings can well become a strong business case in the near future. Due to growing mining volumes, global tailings generation was estimated to total ~3.2 bn tons for copper and ~1.8 bn tons for iron in 2018. It is well known by the mining industry that the cost of tailings management and reclamation are ...

Copper production & environmental impact

Tailings are a slurry of fine-grained rock material and process water. Liquid is removed from the tailings slurry in thickeners and the thickened tailings are discharged to the tailings impoundment. Water is usually reclaimed from the thickeners and recirculated to the mill to be used in beneficiation and dust control (Mining Industry Profile: Copper)

Cut water cost and risk in tailings

To prove the operating and financial benefits of their large format tailings dewatering facility, we partnered with a large mining company in Chile and installed a complete tailings filter system to process approximately 10,000 tonnes per day of whole tailings. A full-scale implementation of this technology would allow mines to operate with a water make-up ratio of 0.2 m3/tonne, compared to ...

Bioteq 2015 Mine Closure - BQE Water : Mine Water Treatment

An important aspect of mine closure is the management of waste residues such as waste rock, tailings, water treatment by‐products and other metallurgical process waste. Issues with waste residues include their mass and volume, long‐term stability and environmental impact, the methods required for safe disposal and the metal value that may be recovered through reprocessing or offtake. Well ...

and water and chemical reagents that remain after processing. The composition of mine tailings varies according to the mineralogy of the ore deposit and how the ore is processed. The tailings are most commonly stored on site in a tailings storage facility. Storage methods for conventional tailings include cross-valley and paddock (ring-dyke) impoundments, where the tailings are behind a raised ...

Recovery of copper from Chilean mine waste waters

Two copper-containing waste-water streams from a Chilean mine site were identified as potential sources of revenue: Source 1 is raffinate from a copper solvent-extraction circuit; Source 2 originates from a reservoir receiving acid mine drainage as a result of natural snow melt. The streams are currently treated with lime to increase the pH for process and environmental purposes; any dissolved ...
