Copper Arsenic Flotation Selectivity

Abstract. The selective precipitation and flotation of copper zinc and arsenic ions from dilute aqueous solutions were investigated. Phase separation was accomplished effectively by the dissolved-air technique for the production of fine gas bubbles and a short-chain xanthate was applied as the collector for copper ions dialkyl-dithiocarbamate for zinc and ferric sulfate for the.

    Jan 05 2021 The poor liberation of copper-arsenic minerals and copper minerals makes selectivity difficult and fine grinding is conductive for the liberation and differential flotation. The FSF slag also contains a trace amount of iron arsenide disseminating finely and existing in the form of micro-granular inclusions that occur in matte and arsenic copper alloys or distributing edgeways.

    The goal of the present work was to develop hydrometallurgical method based on acid leaching which makes it possible to perform selective extraction of non-ferrous metals from old flotation tailings. Leaching was performed with sulfuric acid solutions from 0.5 to 10 and distilled water. Leaching was carried out using percolators and bottle agitator.

    Jul 06 2020 A much more difficult mineral processing challenge is the selective flotation of arsenic-bearing copper minerals e.g. enargite Cu 3 AsS 4 and tennantite Cu Fe 12 As 4 S 13. These minerals have flotation characteristics very similar to non-arsenic-bearing copper minerals chalcopyrite chalcocite and bornite.
