Description

Verfahren zur Trennung des Kupfers von den übrigen in Kupfersteinen und -speisen enthaltenen Iffetallen, wie Blei, Silber, Zinn, Nickel, Antimon usw. Nach bekannten Verfahren werden silberhaltige Kupfersteine geröstet und dann mit Schwefelsäure gelaugt. Es handelt sich hierbei um Kupfersteine, welche bei der Bearbeitung von Kupfererzen, in Kupferhütten fallen und aus Kupfer, Eisen, Schwefel und etwas Silber bestehen.Process for separating the copper from the rest in copper stones metals such as lead, silver, tin, nickel, antimony, etc. According to known methods, silver-containing copper stones are roasted and then with Sulfuric acid leached. These are copper stones that are used during processing of copper ores, falling in copper smelters, and of copper, iron, sulfur and something Consist of silver.

Demgegenüber bezieht sich die Erfindung auf die Bearbeitung solcher Kupfersteine, bei denen erhebliche Mengen anderer Metalle, wie Blei, Antimon, Zinn, Nickel, vorhanden sind und welche vom Kupfer getrennt werden sollen.In contrast, the invention relates to the processing of such Copper stones that contain significant amounts of other metals such as lead, antimony, tin, Nickel, are present and which are to be separated from the copper.

Zu diesem Zweck findet die Röstung und die Laugung unter bestimmten Bedingungen statt, und zwar ist die Behandlung, je nachdem es sich um die Verarbeitung von Steinen oder Speisen handelt, etwas unterschiedlich.For this purpose, roasting and leaching take place under certain conditions, and the treatment is somewhat different depending on the processing of stones or dishes.

Der Kupferstein wird beim Beginn des Röstens auf etwa 35o bis 400' erhitzt, die Speise dagegen auf ungefähr 450'. Diese zunächst geringe Erhitzung geschieht, um das Schmelzen des Ivlateriales zu verhindern. Dann steigert man die Temperatur auf etwa 850'; nach dem Rösten wird das Material gemahlen.The copper stone is heated to around 35o to 400 'when roasting begins, while the food is heated to around 450'. This initially slight heating is done to prevent the material from melting. Then the temperature is raised to about 850 '; after roasting, the material is ground.

Um eine Zementierung bei Behandlung mit Schwefelsäure zu vermeiden, verwendet man für den abgerösteten Kupferstein eine nicht zu schwache, etwa 65 prozentige Säure. Die Speise dagegen wird zunächst mit ###7asser verrührt und dann allmählich mit verdünnter Schwefelsäure in Berührung gebracht.In order to avoid cementing when treated with sulfuric acid, an acid of about 65 percent is used for the roasted copper stone. The food, on the other hand, is first mixed with ### 7asser and then gradually brought into contact with dilute sulfuric acid.

Unter Rühren wird langsam bis zum Sieden erhitzt. Das Kupfer geht in Lösung; die Lauge kann durch Xristallisation auf Kupfersulfat verarbeitet werden, wobei man übrigens ein überaus reines Sulfat erhält. Blei, Antimon, Silber verbleiben bei dem in Schwefelsäure nicht löslichen Rückstande und werden zur gegenseitigen Abscheidung weiteren Verfahren unterworfen.The mixture is slowly heated to boiling while stirring. The copper goes in solution; the lye can be processed by crystallization on copper sulphate, which, by the way, results in an extremely pure sulphate. Lead, antimony, and silver remain in the case of the residues insoluble in sulfuric acid and become mutual Deposition subject to further processes.
