    Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century. It has been described as "the single most important operation used for the recovery and upgrading of sulfide ores". The development of froth flotation has improved the recovery of valuable minerals, such as copper- and le

    Oct 01, 2019· In this study, a flotation tailing produced within an integral process for the treatment of polymetallic sulphide ores is cleaned and valorised seeking a better use of natural resources and a lower environmental impact. In this , bacterial leaching followed by brine leaching is postulated as an alternative to the flotation tailing treatment.

    The great difference between E Cu and E Fe in concentrate and tailing indicates the good separation of copper and iron in the sulfuring flotation beneficiation process. The high E Cu suggests that the addition of sulfiding agent Na 2 S may increase copper recovery ( Sibanda et al., 2020 ).

    Tailings 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 without being processed.. The extraction of minerals from ore can be done two ways: placer mining, which uses water

In the process layout of the flotation tailings beneficiation system, the system itself has the following problems: (1) Since the feed pump flow rate of the new pressurized filter in the concentrator is Q=119m³/h, the flow rate of the underflow pump of the thickener is Q=86m³/h, and one underflow pump needs to feed up to four filter

    It is claimed that the volatile organics used in the Flotation Process do not go into the slurry that goes into the tailings impoundment because they are filtered out before the slurry goes to the impoundment. This is not a sound analysis. 1) Filtration is not a treatment technology for volatile organics.
