  • Characterization of Slags Produced During Gold Melting Process

    Jan 01, 2015  In the extractive metallurgy of gold ores the cyanidation and melting processes are generally applied These processes allow obtaining the “dore” The slag generated during the melting process presents various characteristics, depending on the mineral source and the type of flux usedFeb 28, 2016  The slag contains gold and silver and must be reprocessed in order to minimize the losses of precious metals A very important element in the smelting process is the flux, which is added to charge in order to remove base metals and other impurities from the Dore bar The mixing of charge and fluxes has to be done in ventilated areasGold Smelting Refining ProcessThe Gold Smelting Process Melting, Smelting 18/01/2017 The first step in gold smelting involves processing the gold ore The ore containing gold once mined from the earth is processed by separating gold minerals from the crude matter holding the ore together The gold ore slag from gold ore processing
