gold concentrate retorting smelting and refining

Two (2) major techniques forrefining gold. Generally,goldcan be refined using these two-best-knowngold-refiningprocedures: Aqua Regia andgoldelectrolysis. Both of these techniques can be used to separategoldfrom other metals. This is because a little piece of other metals ingoldcan change its properties and value

    using borax flux to refine gold-manhattan gold & silver

    Aug 07, 2013· In metalrefining, a flux is sort of like a cleaning agent because it helps remove impurities from a sample. With some borax, heat, and a little know-how, it’s possible to extract puregoldfrom a sample of ore. This is because using borax as the flux reduces the melting point of all the elements in a piece of ore, includinggold

    Concentratesare usually specific to particular smelters. Thus a lead smelter or a zinc smelter could not smelt a copperconcentrate(the converse is also true). In fact any copper in a lead or zincconcentrateis generally problematic in thesmelting/refiningprocesses and would most likely incur a penalty charge (see more on penalties below)
