  A novel and clean process for extracting tellurium and bismuth from ...

  202011 · It was found that the complex phase composition of tellurium ores and the dispersibility of tellurium and bismuth in tellurium ores make it very difficult to concentrate. Bio-leaching was also put forward to recover the tellurium and bismuth in tellurium ores ( Lei and Xie, 2012; Guo et al., 2012 ).

  Selective leaching of bismuth from mechanically activated concentrate

  20131112 · The physicochemical changes in the complex sulphide concentrate due to mechanical activation have an influence on the increase in the recovery of bismuth for subsequently thiosulphate leaching. It was possible to achieve ∼99% bismuth recovery within 3 min for a sample mechanically activated.

  The Whys and Wherefores of Penalty Elements in Copper Concentrates …

  It is commonly known that copper smelter terms include penalties if the concentrations of elements, such as arsenic, mercury and fluorine, exceed stipulated limits. It is less commonly known that the behaviour of these elements in the smelters can depend on the processes used to treat the concentrate. The principle behind the penalties is to …

  Lead-Bismuth Flotation - 911 Metallurgist

  The invention relates to a method for extracting bismuth from bismuth concentrate or materials containing bismuth. The method comprises the following steps: bismuth is selectively leached from the bismuth concentrate or the materials containing bismuth; the lixivium is initially purified and reduced; bismuth is extracted from the purified and reduced …

  Optimize flotation process of Mo–Bi sulfide ore for cleaner production

  202141 · The detailed flotation flowsheet and reagent regimes of the industrial-scale tests are depicted in Fig. 6. The contemporaneous samples of feed, concentrate, and tailing were collected every day to assess the flotation performance of sulphide minerals contained in Mo–Bi sulfide ore in froth flotation plants A and B.

  Kinetics and mechanism of selective leaching of bismuth …

  202421 · Through a kinetic study of the hydrochloric acid leaching process applied to bismuth extraction from mixed molybdenite and bismuthinite ore, we have investigated various factors that influence leaching efficiency, such as stirring speed, particle size, acid concentration, and reaction temperature.
