Patent-An Spruch:Patent-An saying: Verfahren zum Auslaugen von kalkhaltigen oder gleichzeitig auch magnesiumhaltigen oxydischen Kupfererzen, besonders von Karbonaten, dadurch gekennzeichnet, daß man diese mit einer verdünnten Lösung von Ätznatron oder -kali behandelt unter Zusatz von organischen Stoffen, die geeignet sind, das Kupferoxyd zu lösen, wie z. B. weinsaure Salze, Trauben- und Rohrzucker und besonders Glyzerin.Process for leaching calcareous or at the same time magnesium-containing Oxydic copper ores, especially of carbonates, characterized in that they are mixed with a dilute solution treated with caustic soda or caustic potash with the addition of organic substances that are suitable for dissolving the copper oxide, such as B. tartaric salts, grape and cane sugar and especially glycerine.
