Recovery Of Iron Ore Tailings Bycolumn Flotation

Recovery Of Iron Ore Tailings Bycolumn Flotation

The exploration of iron ore in small mining companies results in a large amount of unrecovered fine material, representing 35 of the run of mine. Millions of tons of useful minerals are discarded every year into tailings, incurring operation costs, raising production losses and environmental impact. In addition to the disposal of 300 t h of this material, millions of tons are already stored.

Froth Flotation Of Iron Ores

Froth Flotation Of Iron Ores

Jan 02, 2012 Although direct anionic flotation was the first flotation route employed in the iron ore industry, it was later largely replaced by the efficient reverse cationic flotation route. The application of reverse anionic flotation in China in recent years effectively overcomes some flaws of reverse cationic flotation such as high reagent cost and high metal loss in desliming.

Flotation Collectors Optimized Performance

Flotation of iron ore The main objective of iron ore flotation is to upgrade the concentrate by removing silicates and or phosphorus-containing minerals. The use of silica flotation has increased in recent decades. The trend will continue as complex ores have to be mined and higher-grade iron ore concentrates with fewer.

Flotation desliming is using small amount of foaming agent and collector to float part of the slime, then process the coarse-grained flotation. Mechanical desliming is using classifier (such as hydrocyclones) to remove part of the fine slime before flotation. The particle size of desliming is 10-20 microns.
