    • A method for refining gold by a powering process is provided to reduce time and cost to be consumed in a refining process and refine a large amount of gold alloy within a short time by powering a gold alloy such that a gold allow powder is directly reacted with aqua regia, and maximize a gold recovery ratio per unit hour by improving a reaction rate, thereby performing the refining process promptly. A method for refining gold by a powering process includes the steps of: pulverizing a gold alloy comprising impurities; adding aqua regia into the milled gold alloy to dissolve the gold alloy; separating silver chloride from the dissolved gold alloy; and precipitating gold from the gold alloy that has been separated from the silver chloride. The gold alloy is pulverized using an atomizer. The gold alloy contains gold in a content range of 30 to 70% based on the total weight. The gold alloy dissolving step includes the step of heating the aqua regia.

    • PURPOSE: The method for extracting a noble metal is provided which uses relatively strong oxidizer to keep good efficiency and improve productivity through process abridgement. CONSTITUTION: In the extraction method, some of halogen atom or halogen compounds and an oxidizer to oxidize halogen ions are used. Mix reactants including a noble metal with extracts and input them into a reactor. The above reactants and extracts are reacted in the condition of 60 to 80°C by temperature and 1 to 2 kgf/cm¬2 by pressure respectively. Throughout the reaction a noble metal is extracted.
