Improving recovery of iron using column flotation of iron ...

Nov 01, 2020  Primary ether-amines and etherdiamines have been the dominant collectors for the flotation of iron ore since their introduction in the 6s ( Houot, 1983, Araujo et al., 2005 ). Quartz is floated with ether amines (R– (OCH2)3–NH2) partially neutralized with acetic acid. The degree of neutralization is an important parameter.

Reverse column flotation of iron ore SpringerLink

May 01, 2007  高达12%返现  The use of column flotation was considered for the “reverse flotation” of iron ore, where the gangue (quartz) was recovered in the froth product. This use of the froth for carrying the gangue mineral rather than carrying the valuable concentrate significantly changes the operational requirements of the column.
