  • Assay Determination of Arsenic & Antimony

    2017-1-23 · A better method for the separation of arsenic from traces of antimony is the well-known precipitation of arsenic acid with magnesia-mixture. The usual method given by Fresenius gives low results, unless a correction is made for the

  • Arsenic and Antimony Sulphide Minerals in Cyanidation

    2014-9-17 · However, some arsenic and antimony sulphide minerals decompose to some extent in alkaline cyanide solutions to form complex reducing compounds which retard or prevent gold dissolution. It is probable that if the decomposition

  • Removal of antimony from antimony mine flotation

    2011-7-1 · Antimony (Sb) has received increasing environmental concerns due to its potential toxic and carcinogenic properties. In the present work, the electrocoagulation technique was used to treat the flotation wastewater from a heavy antimony polluted area, and the mechanism of removing Sb was also investigated.

  • Selective froth flotation concentration of antimonite ore

    2020-4-16 · antimony 24.89%, lead 0.90% and arsenic 5.89%. The Flame Atomic Absorption Spectroscopy (FAAS) and X-Ray Florescence (XRF) analytical techniques were used to measure the changes in concentrations of antimony, lead and arsenic during this research. Index Terms—antimonite, arsenic, froth flotation, lead. I. INTRODUCTION

  • Extraction of antimony and arsenic from sulphidic

    The flowsheet consisted of mechanochemical leaching in an attritor and further operations as filtration, cementation, antimony precipitation, crystallization and arsenic precipitation. The pilot plant unit was designed for 500 kg per day feed of tetrahedrite concentrate. For the antimony extraction, electrowinning has also been considered.

  • Arsenic and Antimony Removal from Copper

    A water leaching follows the digestion to dissolve the arsenic and antimony, leaving clean copper sulfide solid residues. The laboratory scale tests were carried out using a copper-arsenic concentrate with 15.05% As and 1.42% Sb. The results showed that the most important digestion variables were temperature and concentrations of NaHS and NaOH.
