Froth Flotation of Iron Ores
In the iron ore industry, froth flotation is either used as a primary method for concentrating iron ores, such as Cleveland-Cliffs' operations in Michigan, United States, or in combination with magnetic separation, which has become a popular practice in Minnesota, United States [1]. 2. Iron Ore Flotation Routes

Maximizing the recovery of fine iron ore using magnetic separation - SciELO
A bulk sulphide rougher flotation procedure was conducted on the milled material to generate around 5.5 kg of flotation tailings. The emphasis on a bulk sulphide flotation was to ensure a minimum amount of sulphide reporting to the tailings, since the presence of sulphur in an iron ore product is detrimental.

FLOTATION COST The oil-mixtures generally in use will cost from 1.25c. up to 3c. per lb. depending on the proportion of cresol and other high- priced oils used, but 1½c. per lb. will be a safe average on most oils. A consumption of 1 to 1½ lb. per ton or from 1.25c. to 4.5c. per ton of feed, say 2½c., would be a safe average.

Flotation columns: getting the most from fine ores
Flotation process within a column. Typically, columns are suitable for ores with a particle size bellow 150 µm. Larger particles tend to be too heavy to be kept in suspension. This size limit may vary depending on the ore density. Lighter ores, such as phosphate, are amenable to column flotation at larger particle sizes. Figure 3.

The chemical equation is Al 2 O 3 + 2 NaOH → 2 NaAlO 2 + H 2 O From the above solution, we remove solid impurities by filtration. Then we bubble carbon dioxide through the aqueous solution of sodium aluminate to neutralize it. And aluminium hydroxide precipitates as a result. 2 NaAlO 2 + CO 2 → 2 Al (OH) 3 + Na 2 CO 3 + H 2 O

Ore flotation - Big Chemical Encyclopedia
Oxidized ore particles present must be sulftdized with sodium sulfide to be floated (19). Flotation produces concentrates which are ca 50—60% zinc. In mixed ore, the lead and copper are usually floated after depressing the sphalerite with cyanide or zinc sulfate. The sphalerite is then activated and floated. [Pg.399]

Froth flotation - Wikipedia
Flotation stages [ edit] The first stage is called roughing, which produces a rougher concentrate. The objective is to remove the maximum amount of the valuable mineral at as coarse a particle size as practical. [6] Grinding costs energy.
