What Are The Reagents Used In Direct Flotation Of Iron Ore

Reagents in iron ores flotation - ScienceDirect

Corn starch has been used in iron ore flotation in Brazil since 1978. The trade name of the reagent was Collamil, consisting of a very fine and very pure product. The amylose plus amylopectin content reached 98% to 99%, dry basis, the balance being represented by …

Reagents in iron ores flotation - ScienceDirect

The role of reagents utilised in iron ores flotation is reviewed. Desliming and flotation stages should be performed at pH levels as low as possible to reduce the expenses with caustic soda. Ether amines are by far the mostly utilised class of collector. The degree of neutralisation of the ether amine is an important process parameter.

Reagents in iron ores flotation. The degree of neutralisation of the ether amine is an important process parameter. The partial substitution of amine by non-polar oils seems to be an attractive route. Part of the amine may be also replaced by polyglycols in its frother role. Starches still represent the most important class of iron oxides depressant.

What Are The Reagents Used In Direct Flotation Of Iron Ore

The reagents used in iron ore flotation, including starch, amines and fatty acids, and the mechanisms of their interactions with the minerals in...

direct flotation of iron ore

Investigation of Adsorption Mechanism of Reagents. 3.1.2. Collectors in Direct Iron Ore Flotation. Hematite, goethite and magnetite are the iron oxide minerals, which are separated from the gangue mineral by direct flotation.

Froth Flotation of Iron Ores - sapub

The reagents used in iron ore flotation, including starch, amines and fatty acids, and the mechanisms of their interactions with the minerals in iron ore are examined. The presence of some specific impurities other than quartz in iron ore, such as alumina containing minerals, i.e. kaolinite and gibbsite, and phosphorous, is detrimental and attracts penalties.

Reagents types in flotation of iron oxide minerals: A ...

Jun 10, 2010 · The objective of this review was to present and identify the effects of different flotation conditions on removal of specific impurities in iron ore such as quartz, alumina, phosphorous, and sulfur. Novel and common used collectors, depressants, auxiliary reagents, and their mixtures in the flotation are tabulated.

Investigation of Adsorption Mechanism of Reagents ...

Iron ore flotation started with direct flotation of iron oxides using selected anionic collectors such as petroleum sulphonates, fatty acids and hydroxamates. Direct flotation route was incorporated in the industries in the 1950s in Humboldt Mine, USA (1954), Republic mines USA (1956), Groveland mine USA and Anshan Iron and Steel corporation, China (1958) [ 3 , 4 ].

The entrainment effect on the performance of iron ore ...

As with the anionic route, cationic reverse flotation also uses starch as the iron oxide depressant and specifically for Brazilian iron ore, stone starch has been used widely (Araújo et al., 2005). There is no use of frothers in industrial circuits as the long chain C12 amines play …

Flotation Reagents - Mineral Processing & Metallurgy

Flotation Reagents. The most common way of determining the amount of reagent being used is to measure or weigh the amount being fed per. unit of time, say one minute. Knowing the amount of ore being treated per unit of time, the amount of reagent may then be converted into pounds per ton.

Reagents types in flotation of iron oxide minerals: A review

The objective of this review was to present and identify the effects of different flotation conditions on removal of specific impurities in iron ore such as quartz, alumina, phosphorous, and sulfur.

Froth Flotation of Iron Ores - Publications

The reagents used in iron ore flotatio n, including starch, amines and fatty acids, and the mechanisms of their interactions with the minerals in iron ore are examined.

Hematite Processing by Flotation

The most common reagents are red oil high in oleic acid content, petroleum sulfonates, a frother and occasionally some mineral oil. Emulsions of the first two are sometimes helpful. Flotation is carried out in a neutral circuit unless the phosphorus, usually in the form of apatite, is to be depressed.

Iron Ore Reverse Flotation Introduction - Xinhai

In iron ore direct flotation process, a sort of direct flotation reagent is added and then works under specific conditions. The floating material is mainly iron concentrate. On the contrary, iron ore reverse flotation uses reverse flotation regents to work under given conditions, …
