Fire Assay and Fire AssayingEffects of Flux Materials on the Fire Assay of Oxide Gold Ores

Fire assaying is the quantitative determination in which a metal or metals are separated from impurities by fusion processes and weighed in order to determine the amount present in the original sample Metals recovered in fire assaying are the metals that emerge from the fusion of the material in a assay furnace for gold usually at Fire assay is the most accurate and widely used method for the determination of gold silver and the PGM contents of ores and other solid materials The technique has three steps first step is the smelting of charge mixtures which consist of ground ore samples acidic and basic fluxes lead oxide and a carbon source Isolation of precious
