    This presentation details the research of gold recovery from copper flotation tailings for Mining Negotiation Santa Maria de la Paz Discover the world's research 20+ million membersIt is well known that iron sulphide minerals used as a flotation concentrate, such as arsenopryrite, pyrite, and pyrrhotite are host minerals for native gold, as well as 'invisible gold' [ 7] The conventional cyanidation process and flotation process are widely used for gold recovery from gold ore and gold mine tailingsGold recovery from flotation concentrate from gold mineGold flotation concentrate may contain relatively high concentrations of valuable metals such as iron, copper, and zinc, and occasionally, even precious metals such as gold(PDF) Gold recovery from flotation concentrate from gold

  • Filtration of Copper/Gold Tailings for Mine Backfill BOKELA

    Two BoVac Disc filters L176 are operated in a Gold/Copper Mine in Bulgaria for the filtration of flotation tailings which are used for mine backfill The dewatered and discharged filter cake is mixed with cement and pumped back to the underground to fill the galleriesChemical leaching of the copper and zinc minerals from flotation tailings with sulfuric acid solutions Prior to biooxidation, the samples of flotation tailings were treated in percolators with 5 volumes of 50 mL dilute H 2 SO 4 solutions (pH 124) After passing of the fifth volume of sulfuric acid, the average pH of the eluate was 233Percolation bioleaching of copper and zinc and goldThe gold and copper concentrate product can be recovered once In general, the gold recovery method of gold tailings is mainly the allslime cyanidation CIP method It is the recovery of residual gold particles from tailings by using the property of gold soluble in cyanideGold Tailings Reprocessing Technology xinhaiepc

    Since gold is usually symbiosis with chalcopyrite, sphalerite, galena, etc, and with the different content of each element of the ore, the symbiotic ore will also be different Usually, copper, lead, and zinc are comprehensively recovered after gold cyanidation #2 Tailings Fillingcopper sulfide and free oxidation copper in the raw ore were recycled by flotation, but the other refractory copper oxides, mainly the combination copper oxide, were not thoroughly recycled and the majority were lost in the tailings As is typical for flotation tailings containing silicate gangue minerals, high temperature leaching was used [12]Copper Leaching from Refractory Flotation TailingsThe pyrite grade in the fresh tailing sample and in the flotation product was determined indirectly from the content sulfur, copper and iron Calculations carried out considering the elemental chemical composition presented in Table 1 and the mineralogical species that contained sulfur, identified by the XRD analysis, allowed to determine that the fresh tailings sample contained 456% FeS 2Recovery of pyrite from copper tailings by flotation

  • RECOVERY OF COPPER FROM COPPER SLAG AND

    Abstract: Copper smelter slag and copper smelter slag flotation tailings were leached using sulphuric acid solutions, without or with the addition of either ferric sulphate or hydrogen peroxide Copper extraction from the slag was typically found to be twice as high as that from the slag flotation tailings Hydrogen peroxide was determined to be the best lixiviant Thus, copper and iron extractions were 634% and 486%, respectively, when leaching the slag with 3 M H2O2, after 120 minutes of reaction at room temperature CopperThe present study investigates the effect of regrinding and aeration on the separation of pyrite from gold in copper rougher flotation tailings (007% Cu, 061g/t Au, tail grades) An aeration stage was applied both at the head of copper flotation (copper rougher feed) and after regrinding of the copper rougher tailings, before gold/pyrite selective flotationPyritegold recovery in copper rougher flotation tailings• Install a HydroFloatTM circuit to treat the full flotation tailings stream from Train 3 (T3) of the Concentrator 1 flotation circuit (~9Mtpa) • Primary objective to recover gold and copper previously lost to T3 tailings in coarse composite particles (+150 µm),HydroFloatTM Case Study: Copper Recovery from
