摘要:
Die Erfindung betrifft ein Verfahren zur Herstellung eines Aufbereitungssammelkonzentrats zur Ausbringung von Edelmetallen aus Ton- und Salzabfällen (Schlämmen) von Betrieben, welche Kalium-Magnesiumerze und Steinsalz verarbeiten. Das Verfahren zur Herstellung eines Sammelkonzentrats zur Ausbringung von Edelmetallen umfasst eine Dreistufenbehandlung der Schlämme in einem Hydrozyklon unter Ausscheidung des Konzentrats. Das nach der Behandlung im Hydrozyklon hergestellte Sammelkonzentrat stellt eine Mischung von Absetz- und flotierbarem Material im Verhältnis Feststoff : Flüssigkeit von 1 : 1 dar und wird verfahrensgemäß entwässert, sich etwas abtrocknen lassen, granuliert und danach getrocknet.
摘要:
The present invention provides an alkali metal and/or alkali earth metal extraction method that has excellent extraction efficiency and allows repeated use of an aqueous solution that extracts an alkali metal and/or alkali earth metal from a solid. The alkali metal and/or alkali earth metal extraction method is a method for extracting an alkali metal and/or alkali earth metal from a solid containing the alkali metal and/or alkali earth metal, the method including an elution step in which the solid is added to a neutral amino acid-containing aqueous solution or an amino acid-containing mixed aqueous solution produced by mixing a pH adjusting agent with an aqueous solution containing at least one of a neutral amino acid, an acidic amino acid and a basic amino acid so as to elute the alkali metal and/or alkali earth metal in the neutral amino acid-containing aqueous solution or the amino acid-containing mixed aqueous solution.
摘要:
A method for the removal, separation, and concentration of alkali metal, alkaline earth metal, Pb and/or Tl cations from a source solution which may contain larger concentrations of other ions which comprises bringing the source solution into contact with a compound comprising an oxygen donor macrocycle-containing ligand covalently bonded through an organic spacer silicon grouping to a solid inorganic support.

In one aspect, the present invention is directed to methods and apparatuses for recovering target metals from scrap. In some embodiments, the methods comprise dissolving a portion of a mixed metal scrap into a molten salt to form a molten salt and metal mixture, the scrap including a target metal species and at least one contaminant metal species; bubbling a gas through the molten salt and metal mixture to form a gas and metal vapor mixture comprising target metal vapors; and condensing at least a portion of the target metal vapors.
