Starting with an containing antimony 589 lead 034 and arsenic 025 a concentrate containingantimony 3068 lead 152 and arsenic 085 wasMore Details
Arsenic antimony and bismuth are three metalloids that usually occur together in association with copper lead tin and gold ores Bolivia is the only country in the world where bismuth is found in sufficient concentration to justify mining for bismuth alone while in Morocco both arsenic oxide and metallic cobalt are recovered from a uniqueMore Details
Nov 01 2014 · 11 Arsenic problems in copper flotation As metal reserves around the world and existing mines get deeper ore mineralogy is becoming increasingly more complex In addition penalty elements such as arsenic antimony and bismuth are occurring in increasing concentrationsMore Details
The technology of concentration of the sulfide antimonyarsenic goldbearing ore containing 36 gtn Au 03 Sb and 04 As is developed This technology implies the flotation separation ofMore Details
media The flotation of goldbearing iron sulfide FeS 2 and FeAsS may be activated by small additives of CuSO 4 · 5H 2 O which have an additional depressing influence on Sb 2 S 3 in the alkali medium The selection of bulk concentrate obtained during the flotation of antimony and goldarsenic ores is carried out by the depression of eitherMore Details
The study Arsenic trisulfideArsenic III trisulfide As2S3 has a very limited solubility in water eg 1 mgL at pH 4 and is relatively stable under anoxic and reducing conditionsMore Details
Jan 01 1989 · The original intention was that antimony flotation should be followed by arsenic flotation with CuSO4 activation with a view to recovering any remaining refractory gold However this process ran into difficulties and was not put on steam The quality of the antimony concentrate can be seen from the figures in Table 3More Details
Jun 18 2007 · Copper is often associated with arsenic in mixed sulphide minerals such as enargite Cu3AsS4 and tennantite Cu12As4S13 Enargite in particular is the principal mineral in many deep epithermal copper–gold deposits Most mining companies avoid exploiting such resources because the arsenic can become a serious environmental liability or may considerably reduce the resource valueMore Details
Arsenic sulfides occurring in nature are realgar As 4 S 4 orpiment As 2 S 3 arsenopyrite FeAsS and enargite Cu 3 AsS r can be distilled without decomposition while orpiment melts at 310 °C and boils at 707 °C without decomposition Both are insoluble in water and acids even in concentrated HCl but dissolve readily in alkaline reagents especially alkali sulfide solutionsMore Details
