    • The invention relates to a method for refining gold containing metallic impurities. According to said method, the proportion of metal oxides is increased in a targeted manner by annealing the gold at preferably between 450 and 550 DEG C for between 1.5 to 2.5 hours. The gold is then treated with concentrated hydrochloric acid at a controlled redox potential, enabling a large part of the metal oxides and metals to dissolve immediately. In order to create identical reaction conditions, the gold used preferably has essentially the same particle size or gold concentration. Air can then be guided through the softened gold, in order to oxidise the previously formed monovalent copper chloride in a strong exothermic reaction. Said reaction is monitored by measuring the temperature and is optionally controlled as required. The gold is then post-treated with concentrated hydrochloric acid and a small amount of hydrogen peroxide at a controlled redox potential, and the purification effect can be controlled by the mixing ratio of said two substances. The refined gold is then washed with concentrated hydrochloric acid and deionised water and, according to requirement, is either further purified by a subsequent fine refinement method or is directly supplied elsewhere for a different use. The inventive method is especially suitable for the refinement of powdery, ground, small-particle, film-type or wire-shaped gold.

    • The present invention concerns a process for refining silver bullion, i.e. raw silver containing generally more than 90 % silver besides Se, Pb, Au, Cu and platinum group metals (PGM) as main impurities. The process comprises the steps of: optionally removing Se as gaseous SeO2 from the molten metallic phase by injecting air, which is preferably O2 enriched, into the metallic phase at a preferred bath temperature of 1000-1100 DEG C; optionally slagging off the Pb by contacting the molten metallic phase with a silica and borax based flux at a preferred bath temperature of 1000-1150 DEG C; granulating the molten metallic phase in water, thereby forming Ag rich granules; leaching the Ag rich granules with HNO3 at a temperature above 50 DEG C, preferably in an O2 enriched atmosphere, followed by filtration, thereby separating an Au bearing residue from an Ag rich liquor; heating the Ag rich liquor, thereby evaporating H2O and forming an AgNO3 bearing melt; maintaining the AgNO3 bearing melt at a temperature of 220-350 DEG C for at least 15 minutes, thereby forming a mixture of a purified AgNO3 and of a denitration residue containing essentially all the PGM as oxides; separating the purified AgNO3 from the denitration residue. By this process, the many drawbacks of the classical electrolytic refining of silver are avoided.
    • 本发明涉及一种精炼银锭的方法,即除了Se,Pb,Au,Cu和铂族金属(PGM)作为主要杂质之外,通常含有超过90%的银的原料银。 该方法包括以下步骤:在优选的浴温为1000-1100℃下,通过将优选富O2的空气注入金属相中,从熔融金属相中任选地将Se作为气态SeO 2去除; 在优选的浴温为1000-1150℃下,通过使熔融金属相与二氧化硅和硼砂基焊剂接触,可选择地除渣; 将熔融的金属相制粒在水中,从而形成富含Ag的颗粒; 在高于50℃的温度下,优选在富含氧气的气氛中用HNO 3浸出富含Ag的颗粒,然后过滤,从而将富含Ag的残留物与富含Ag的液体分离; 加热富含Ag的液体,从而蒸发H 2 O并形成含有AgNO 3的熔体; 将AgNO 3轴承熔体在220-350℃的温度下保持至少15分钟,由此形成纯化的AgNO 3和基本上所有PGM作为氧化物的脱硝残渣的混合物; 将纯化的AgNO 3与脱硝残留物分离。 通过这个过程,可以避免经典的电解精炼银的许多缺点。
