  A Selective Method for Chemical Extraction of Antimony …

  2022116 · Antimony leaching from tetrahedrite-bearing ores was typically carried out by using Na2S-NaOH solutions. In the current paper, the detail mechanism of antimony leaching from tetrahedrite-rich concentrate via K2S and BaS lixiviants was investigated for the first time. Sample was characterized in terms of chemical, mineralogical, and …

  Selective froth flotation concentration of antimonite ore …

  Froth flotation process is used to concentrate relatively low grade ores. In Zimbabwe antimonite is mined together with lead and arsenic which are regarded as contaminants and hence the need to selectively remove them. We report on the selective concentration of antimonite at the expense of lead and arsenic by use of a depressant.

  Distribution and migration of antimony and other trace …

  201881 · Antimony (Sb) usually occurs associated with arsenic, lead, and other metal elements in sulfide deposits, and most is currently being extracted from the Karst areas, southwest China. In these areas, the acid generated from the oxidative dissolution of sulfide minerals is neutralized by the abundant carbonates but little is known about the effect of …
