Reverse column flotation of iron ore SpringerLink

May 01, 2007  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. The objective of this work was to determine which of several column flotation ...
