The Mining Process OceanaGold
网页The ore now goes through a three-stage processing cycle to ensure the gold is economically recovered from the ore. Stage 1: Crushing and Grinding Ore stockpiled from underground and open pit mines is fed into the primary crusher at the process plant. The jaws inside crush the rock down to fit through the 125mm gap at the bottom.

Production of Gold West Virginia University
网页The smelting step of refining consists of heating the loaded steel wool to melt the gold at 1300°C, with fluxes of silica, feldspar, and borax, to remove impurities. Complete separation occurs within 1.5 hours, at which point the slag is poured off and the molten gold is poured into anode casts and cooled.
