  • Gold parting Wikipedia

    Gold parting as a process was specifically invented to remove the silver. The main ancient process of gold parting was by salt cementation and there is archaeological evidence of that process from the 6th century BC in Sardis, Lydia. In the post-medieval period parting using antimony, sulfates and mineral acids was also used.

  • Parting | metallurgy | Britannica

    Parting, in metallurgy, the separation of gold and silver by chemical or electrochemical means. Gold and silver are often extracted together from the same ores or recovered as by-products from the extraction of other metals. A solid mixture of the two, known as bullion, or doré, can be parted by boiling in nitric acid.The silver is dissolved as silver nitrate, leaving a residue of gold that

  • Five Common Gold Separation Methods You Have to

  • Separation of Gold from Other Metals in Thiosulfate

    The extraction of gold, silver, copper, zinc, and nickel present in thiosulfate solutions with or without the presence of ammonia was studied. Results show that neither a primary amine nor the mixed extractants of a primary amine with tributyl phosphate or trialkyl amine oxide can separate gold from other metals in the absence of ammonia in aqueous solutions.

  • Extraction of Gold

    When the gold has solidified, the molten silver chloride collected on the surface is run off, carrying with it a small proportion of gold. When silver is the chief impurity in the gold, as in that found in Australia, the process is specially applicable. The gold has a degree of purity of 99.1 to 99.7 per cent.

  • Membrane Separation | Veolia Water Technologies

    MEMBRANE SEPARATION PROCESSES. Membranes allow certain molecules or ions to pass through by diffusion and sometimes by specialised ‘facilitated diffusion’. The rate of passage depends on the pressure, concentration and temperature of the molecules or solutes on either side of the membrane, as well as the permeability of the membrane to each solute. This depends on solute size, solubility
