  Verfahren zur   HersteIluHa. eines Chromerzkollzenfates.   



   Bekanntlich lassen sich alle oxydischen Erze und auch die meisten Gangartmineralien bei Auswahl der geeigneten Bedingungen mit höheren Öl- oder Fettsäuren und deren Salzen flotieren. Bei allen oxydisehen Erzen ist demnach die Gefahr vorhanden, dass gleichzeitig mit den   nutzbaren Erzteiichen

 behandlung mit einer   komplexen     Heteropolysäure. insbesondere Phosphomolybdänsäure,   unterwirft. 



   Bei der nachfolgenden. Aufbereitung lassen sich dann die bei der Flotation   üblichen     Zusätze, wie   01-und Fettsäuren, sowie die verschiedenen im Handel befindlichen speziellen Flotationsmittel verwenden,

 Trennung erzielt werden kann. 



   Beispiel :   l   Icg Chromeisenstein wird in Anwesenheit von Wasser der   Einwirkung von 0#135 g Phospho-   molybdänsäure unterworfen, worauf man als   Sammler 0#8-1 g Na-Palmitat und   als Schäumer   0'02 g     Eiefernol.   (Pineol) zusetzt. Letztere liefern den   Schaum,   in welchem sich das Erz frei von der Gangart ansammelt. Es empfiehlt sich. als weitern Zusatz   0-1 Wasserglas beizufügen, worauf   man den Flotationsprozess in bekannter Weise vor sich gehen lässt.

  Process for the manufacture. of a chromium ore.



   It is known that all oxidic ores and also most gangue minerals can be floated with higher oleic or fatty acids and their salts if the appropriate conditions are selected. With all oxidic ores there is therefore the danger that simultaneously with the usable ore pools

 treatment with a complex heteropoly acid. especially phosphomolybdic acid.



   In the following. Processing, the additives customary in flotation, such as oil and fatty acids, as well as the various special flotation agents available on the market can then be used,

 Separation can be achieved.



   Example: Icg chrome iron stone is subjected to the action of 0 # 135 g phosphomolybdic acid in the presence of water, whereupon 0 # 8-1 g Na palmitate as a collector and 0'02 g Eiefernol as a frother. (Pineol) adds. The latter provide the foam in which the ore collects free of gangue. It is advisable. add 0-1 water glass as a further addition, after which the flotation process can be carried out in a known manner.
 EMI1.3
 Use phosphotungstic acid.
