  • home made cupels Page 1 Gold Refining Forum

    I've tested the lead oxide layer in some with a reducing flame and can get the lead to reform into metal form again. I don't want to just throw them away since they contain some gold/silver/etc. and I figure the lead oxide is probably more dangerous than the lead metal.

  • A Guideline to Reducing Inorganic Lead Exposure

    Lead oxide (litharge) is an important component of the flux material used in the fire assay process to aid in separating target precious metals from the ore.

    Copper May be reduced to the metal during fusion and reports in the lead button. This can then inhibit cupella This can then inhibit cupella tion, making it impossible to recover the precious metals.

    My goal is to recover 10 to 15 grams of gold, 7 to 10 ounces of silver, minor copper (perhaps a few ounces) and a number of pounds of lead (the lead will be used to cast bullets). I may also attempt to recycle the zinc and copper I consume in the Parkes and silver cementation steps.

  • Enhancement of gold recovery during lead fire assay by

    The aim of this study was to investigate the effect of a simple and economical saltroasting method on the gold recovery of a conventional lead fire assay. An enhanced gold recovery of 30.99 g/ton (16.82%) was obtained by roasting a gold concentrate at 750°C, but this was further enhanced to 40.44 g/ton (21.95%) at the same temperature with

  • Gold Smelting Refining Process

    If we have to know about gold assay, it is important to mention the Fire Assay Process that has been employed in the mining industry for a long time. Basically the ore is mixed with a mixture of fluxes and during the smelting process precious metals are liberated and most of heavy metals

  • Assaying Ores to determine gold content

    Testing and analyzing your ore to assay its gold and silver content: Nevada Outback Gems. This mass of lead metal contains all the gold and silver was present in the sample. The mass of lead metal is then placed on a cupel made of bone ash. This is necessary to be sure that you will recover all the gold in the sample.

    Any of these nonstandard Recovery methods require a lot of testing to achieve the ideal balance of Chemical vs Metal to reach the desired result of recovering more Gold. There would have to be a significant amount of Gold being lost in those Tails though to justify setting up anything more complicated than a standard Gravity system, particularly if it involves Chemical extraction.
