magnetic flotation of iron ore

Cationic flotation of silica from magnetic iron-ore ...

Twelve cationic, amine-salt silica-collectors were evaluated on three samples of magnetic iron-ore concentrate. Coco primary amine acetate was used as the standard of comparison. Lauryl primary amine acetate is somewhat more efficient in collecting silica than the standard, and equally selective. Tallow primary amine acetate is equally selective and somewhat less efficient than the the ...
