Abstract

Oppfinnelsen vedrører en omvendt flotasjonsprosess for behandling av en kalsiumkarbonatmalm som inneholder silikater. Prosessen omfatter bruken av to samlere selektert fra gruppen bestående av fett/tri-lavere alkyl kvartære ammoniumforbindelser, fett/di-lavere alkyl/benzyl kvartære ammoniumforbindelser, fett/lavere alkyl/di-benzyl kvartære ammoniumforbindelser, di-fett/di-lavere alkyl "quat"-forbindelser, di-fett/lavere alkyl/benzyl "quat"-forbindelser, og fett/bis-imidazolin "quat"-forbindelser. Anvendelsen av en kombinasjon av forskjellige "quat"-forbindelser ble funnet å resultere i en synergetisk ytelse av samlerne.
