Iron Ore Clariant . In Reverse Iron Ore Flotation, Clariant has been developing a comprehensive range of collectors for iron ore flotation to remove undesirable silicate minerals impurities. The FLOTIGAM174; series includes ether amines, used for hematite iron ore, and ether diamines, used for .
Jun 1, 2011 Other types of chemicals used include depressants, which form a polar chemical envelope around particles and depress the effect of any hydrophobic . Clariant has a long history of providing collectors (Flotinor, Hostaflot), depressants (Flotol) and frothers (Flotanol, Montanol) for .
Clariant. Clariant has a long history of providing collectors (Flotinor, Hostaflot), depressants (Flotol) and frothers (Flotanol, Montanol) for the mining flotation process. It also supplies the Arkomon range of products for dust control.
For the beneficiation of lowgrade phosphate ores containing low silica, ferric oxide, aluminum oxide, magnesium oxide, and calcium oxide contaminants, Clariant has developed new anionic collectors that provide higher recoveries and grades than the traditional fatty acid anionic collectors commonly used around the world for semisoluble salt minerals.
Flotation equipment technology screening922 Кб. Pneumatic flotation is however still considered as a nonconventional flotation process. Due to its highly selective nature in operation it has generallyCMH spent considerable time on developing a reverse flotation process and a reagent suite to try and reduce the silica content to acceptable levels.
May 07, 2009· This invention relates to the use of a compound of the formula (I) where R 1 is a hydrocarbon group having 140 carbon atoms, R 2 is an aliphatic hydrocarbon group having 24 carbon atoms, and also R 3 is an alkoxy group, n is in the range from 1 to 50, and m is 1 or 2, as flotation reagent in silicate flotation . R 1 —O—R 2 —NH (2m) —[(R 3) n —H] m (I)
The present method allows for the quantification of amines etheramine Flotigam EDA 3B and etherdiamine Flotigam 2835, which are produced by Clariant and are used in the flotation process by several mining companies. According to Clariant's datasheet [Empresa Clariant .
Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and wastewater treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.
Examples of quartz and feldspar flotation with cationic amine collectors indicate that these minerals must be effectively depressed for selective flotation to occur [5460]. Calcium lignin sulfonate (Goulac), a silicate depressant, is commonly used in muscovite flotation [61, 62].

Reverse cationic flotation was carried out to float silica and alumina gangue using amine based cationic collector. Potato starch was used as a depressant for iron bearing minerals. Sodium hydroxide was used as a pH regulator. In direct flotation fatty acid as collector and pine oil as frother was used.
The alkyl amines usually used as collectors in kaolinite flotation processes only give satisfactory results in strongly acidic systems based on cationic surfactants were developed to ...
Reverse cationic flotation removes quartz using ether amine as a collector, while depressing iron oxide with the use of corn starch in alkaline pulp adjusted by NaOH. In most cases, the pH ranges from 10 to In early years, primary fatty amines such as dodecylamine were used in reverse cationic flotation.
Iron Ore Clariant Ltd. In Reverse Iron Ore Flotation, Clariant has been developing a comprehensive range of collectors for iron ore flotation to remove undesirable silicate minerals impurities.

An impure crude kaolin clay is initially subjected to wet processing including a size classification step, to recover a beneficiated fine particle size kaolin fraction which is formed into a ...
Commonly used collectors include lowcost soaps, fatty acids, amines, quaternary ammonium compounds, sulphonates and petroleum oils. Frothers are surface active (surfactants) reagents added to the pulp to reduce the surface tension of air bubbles and help stabilise the mineral froth. Commonly used frothers include pine oil, alcohols
