  • Process for the recovery of gold using plasma

    A calcined gold bearing ore, containing from 250 to 350 ppm of gold, was subjected to cyanidation. The residue from this cyanidation step, which contained 25 ppm gold, was dried and blended with a flotation concentrate, lime and carbon and fed to a plasma arc furnace. The flotation concentrate contained 212 ppm of gold.

    01/08/2021 · 1. Introduction. The depletion of large oxidized‑gold deposits triggered the processing of refractory ores, where the precious metals are associated with sulfides and other compounds of base metals, antimony or arsenic (Jha and Kramer, 1984).There are several alternatives for the treatment of refractory minerals, which have been studied for several decades (Chilton, 1958; Sill, 1960; Bhakta ...

  • Arsenic trioxide

    Most arsenic oxide is, however, obtained as a volatile byproduct of the processing of other ores. For example, arsenopyrite, a common impurity in gold and coppercontaining ores, liberates arsenic trioxide upon heating in air. The processing of such minerals has led to numerous cases of poisonings.
