In iron ore flotation process, a large amount of naoh is taken to adjust the ph. the wastewater ph of iron ore is more than 9, so physicochemical treatment of iron wastewater from a certain degree is rather difficult 9. at present, the common methods of treatment of wastewater from flotation are acidalkali neutralization 10,11.

Froth Flotation Of Iron Ores

With the depleting reserves of highgrade iron ore in the world, froth flotation has become increasingly important to process intermediate and lowgrade iron ore in an attempt to meet the rapidly growing demand on the international market. in over half a centurys practice in the iron ore industry, froth flotation has been established as an efficient method to remove impurities from iron ore.
