chemical ore processing of silver

In order to ensure complete dissolution of the silver, the silver content of the bead should be at least 60–70 percent. A process routinely employed in thefire assayingofgoldores is the addition of silver prior to fusion of the ore in order to ensure that the silver content of the final bead is high enough to dissolve. This is called inquartation, and the separating of silver and gold by leaching with nitric acid is …

    The salt (NaCl) reacts with the silver sulfide (Ag2S) in the open air and light to form silver chloride (AgCl): Ag2S + 2NaCl + 2O2 = Na2SO4 + 2AgCl. Then, the silver chloride (AgCl) reacts with the mercury (Hg) to form silver metal. 2AgCl + 2Hg = 2Ag + Hg2Cl2. This process was carried out in the light and open air.

  • Extractive Metallurgy Introduction to Chemistry

    Extractive Metallurgy. Extractive metallurgy is the practice of removing valuable metals from an ore and refining the extracted raw metals into a purer form. In order to convert a metal oxide or sulfide to a purer metal, the ore must be reduced physically, chemically, or electrolytically. Extractive metallurgists are interested in three primary streams: feed, concentrate (valuable metal oxide/sulfide), and tailings …
