Investigation of the effect of cyanidation after microwave roasting treatment on refractory gold/silver ores by characterization studies

In this article, the efficiency of microwave pretreatment, which is an environmentally friendly, low-energy consuming method for recovery from refractory gold-silver ores, was investigated. The ore sample belonged to oxidized Bolkardağ deposit, contains carbonate (calcite, dolomite, smithsonite, hydrozincite), silicate (quartz, hemimorphite), sulfate (beudantite, plumbo-jarosite), and iron oxy/oxyhydroxide (hematite, limonite) minerals. Sulfur/sulfate-bearing silver gold minerals are found either together with gangue or in inclusions. Approximately 90% 48% efficiencies were achieved cyanide process after preroasting ore. Additionally, ore, heat treatment product, waste samples investigated by characterization studies. these studies, bond structures, mineral content, mass losses, element percentage content differences, differences determined. As a result, pretreatment application cyanidation presented as new research topic terms its valuable type oxide.
