In copper mining, the volume of tailing waste was estimated 95 to 99% of the crushed and ground ores (Edraki et al. 2014). Mining and processing of low-grade deposits, such as Cu-porphyry ores ...
Task 4. Mine Tailings ReuseNew Mexico State University. For copper mines tailings are created when the copper ore is finely ground to liberate the copper minerals from the host rock. The copper minerals are recovered and the finely ground host rock is sent to tailing repositories as a slurry where they consolidate into a large earthen dam.

These tailing are stored and handled by various methods such as ponds, dams, dry piled or filled back to where it came. In todays mining operations the storage and handling of tailings is a big issue. The big problem for engineers and mine planners is always the same. Where and how to dispose of tailings.
15-05-2017· By doing this with no pH adjustment to the leachates, copper was selectively removed, as other metals present in significant concentrations in the leach liquors (iron and zinc) do not form sulfide phases at pH values <3. This approach would therefore facilitate the recovery and recycling of copper from both mineral tailings wastes.
