The Silver Extraction Process The ore used to extract silver was not a silver ore but Lead Sulphide (formula PbS), known as Galena or Galenite (named by the Roman Pliny) which contains 87% lead The local variety of Galenite is silver-bearing and is known as Argentiferous Galenite (formula (PbAg)S) and the lead obtained from this ore.

Sulfide Ore Treatment Gold - Silver - Copper - Cobalt ...

2017-10-20  A procedure was developed for recovering gold, silver, cobalt, copper, and zinc from a massive sulfide ore by a hydro-metallurgical process. The procedure consists of (1) oxygen pressure leaching; (2) iron, arsenic, and copper removal from the leach solution by precipitation; (3) selective extraction of cobalt and zinc from solution; (4) electro-deposition of the cobalt and zinc from the strip liquor; and (5) cyanidation of the pressure leach residue to recover gold and silver.

2021-5-3  They said it had a lot of silver and copper, but no gold. A geologist said that the fire assay may not have extracted the gold from the ore, because of the various gold-silver-copper sulfur refractory compounds within due to a limited process that was used. This type of ore requires more extensive process steps to reduce the gold.

SMELTING SILVER - rocks4brains

2015-8-5  Washing the ore is more straight-forward: it dissolves all soluble salts5 and many clays, most of which are unwelcome contaminants during smelting. Since silver minerals are relatively dense, they sink to the bottom of the bath. The dissolved salts and clays are then removed by pouring off the wash water. This cycle is repeated until the water is clear.

The effects of silver sulfide (Ag2S) on the bioleaching of chalcopyrite and pyrite were investigated in this paper. It has been shown that Ag2S enhanced the yields of bioleaching of chalcopyrite but inhibited the bio-oxidation of pyrite. The addition of Ag2S selectively increased the copper dissolution from the chalcopyrite-containing ores in shake flasks with a recovery of 85.3% compared with ...
