  A selective process for extracting antimony from refractory gold ore

  201751 · To avoid the adverse effects of antimony on the cyanide leaching process used for the recovery of gold from refractory gold ore, a cleaner production process was proposed that would selectively remove antimony as sodium pyroantimonate. The process included three steps: 1) leaching of antimony from the refractory gold ore with sodium …

  Antimony recovery from SbCl5 acid solution by hydrolysis and aging ...

  2015514 · This study aimed to find an efficient way to recover Sb from the SbCl5 acid solution obtained by the chloride leaching process of the tin-depleted residue. Sb was recovered in the form of hydrated antimony pentoxide through the hydrolysis process. The effects of hydrolysis ratio and aging time on the Sb recovery process were studied, and …

  Process flow-sheet for gold and antimony recovery from …

  2000101 · Introduction Generally, extraction and recovery of antimony are realised by pyrometallurgy, which involves the evolution of toxic gases into the atmosphere; several hydrometallurgical methods have been proposed [1], [2], [3]. Different leaching agents can be used for treatment of stibnite (Sb 2 S 3) ore: mixture of hydrochloric and tartaric acids, …

  Trend and recovery of arsenic, antimony and bismuth in …

  In this paper, the impurity elements such as arsenic, antimony and bismuth in the copper smelting process were used as research objects. By comparing and analyzing the actual production data, a preliminary understanding has been made of the distribution of arsenic, antimony and bismuth in different processes in the copper smelting. The results show that …

  Antimony Recovery from Complex Copper Concentrates …

  Today, one of the major difficulties confronted during copper metallurgy is the elimination of antimony and arsenic impurities from the process. This is because the pure copper ore reserves are becoming exhausted and the resources of unexploited ores often contain relatively high amounts of antimony and arsenic. During smelting of copper concentrates, …
