Selective separation of gold from iron ore samples using ...

2003-12-1  The use of certified reference material, gold standard solutions and gold radioactive tracer 198 Au has shown that the separation efficiency of gold from iron is very high where the selective coefficient K Fe Au is found to be ≈6.4×10 11. Also, the resin capacity of gold tetrabromoaurate has been measured and found to be ≈1.2 m eq/1 g resin.

Extraction of Gold

In the electrolytic precipitation of the gold an iron anode and a sheet-lead cathode are employed, the current-density being very low, about 0.5 amp. per sq. metre. The gold is deposited on the lead, and after removal of this metal still contains a considerable proportion of both lead and silver.

Extracting antimony from high arsenic and gold

2019-6-1  Gold and aresenic remained in the leaching residue, which was further used as a raw material for gold extraction. Thus, the separation of antimony from gold and arsenic was achieved. The cathode metal antimony contained >98% antimony and less than or equal to 0.21%, 0.03%, and 0.14% of As, Fe, and Au, respectively.

Separation of Gold from Sulfide Using a Plasma Arc

Transferred-arc plasma treatment of iron sulfides containing gold is examined from both thermodynamic and experimental points of view. Three cases are analyzed: argon plasma with sulfide, argon plasma with a carbon–sulfide mixture, and argon–methane plasma with sulfide. The carboreduction of the materials appears to be well adapted for gold separation by fuming, but experimentally the ...
