Abstract
A research project supported by the Minnesota Department of Natural Resources and the
Iron Ore Cooperative Research Committee was undertaken to 1) evaluate the problems
related to cation exchange mechanisms that occur during wet grinding, flotation and
balling and 2) investigate ionic formation and precipitation that occurs in the processwater
during taconite processing.
The cation exchange capacities of rod mill feed samples from two taconite plants were
determined. Ball mill grinding, magnetic separation, bench scale flotation and balling
tests were performed to establish the effect that cation exchange has on flotation and
balling. Tests indicate that balling and flotation are affected by the cation exchange
capacity of processed taconite ore. The rate of formation of sulfate, fluoride and
bicarbonate anions during the grinding of taconite rod-mill-feed was determined. Sulfide
oxidation to sulfuric acid followed by neutralization with carbonate minerals was studied.
Fluoride liberation from the taconite ore was also investigated.
