Extraction Of Gold By Chlorination

  • Extraction of Gold - Element Gold, Au, Transition Metal

    Bromine acts more energetically than chlorine, and has also been employed in the extraction. The recovery of the gold is effected similarly, and the bromine is then liberated by the action of chlorine, but it is impossible to prevent loss of bromine. Cyanide-process The extraction of gold by the cyanide-method is of great technical importance.

    ABSTRACTThe selective chlorination of cyanidation tailing (CT) for the extraction of gold and silver has been investigated. The reaction operated at different conditions and their effect on the extraction of Au and Ag was studied. The mineral samples were characterized by fire assay, X-ray diffraction (XRD), X-ray fluorescence (XRF) and scanning electronic microscopy (SEM).

    Jul 08, 2019 · Yes, it is possible to extract gold from seawater in theory, but it's really not practical to do so. It is estimated that there is, in total, about eight million tons of gold dissolved in the world's oceans. While this is a lot, the oceans are huge, and the actual concentration of gold in seawater is only about 0.0000000006%. To put it .
