Definitions
- the present invention relates to the use of collectors in the flotation treatment of silicate-containing minerals and ores, in particular iron ore with the aid of fatty alkyl ether alkylamine alkoxylate.
- silicates are naturally occurring ores and minerals.
- these include calcite, phosphate ore and feldspar.
- the silicate content reduces the quality of the iron ore and interferes with iron production.
- the iron ore is separated from the silicate in addition to the magnetic separation by inverse flotation.
- the ground iron ore is brought together in a flotation cell with water and flotation reagents, wherein the silicate is discharged through the use of a collector with the foam, while the iron ore remains back in the so-called pulp.
- fatty amines alkyl ether amines and alkyl ether diamines are used as silicate collectors. These are known under the trade name Flotigam ®.
- Alkyl ether amines and alkyl ether diamines are mostly used in their partially neutralized forms as partial acetates as described in US Pat. No. 4,319,987. The reason for this is the better solubility of the partially neutralized amine functions.
- WO 00/62937 discloses the use of quaternary amines for flotation of iron ore.
- WO-93/06935 describes the synergistic effect of ether amines and anionic collectors for iron ore floatation.
- silicate flotation collectors described in the prior art show insufficient selectivity and yield.
- the object of the present invention was therefore to provide an improved collector for the silicate flotation.
- the invention thus relates to the use of a compound of the formula (I)
- R 1 is a hydrocarbon group having 1 to 40 carbon atoms
- R 2 is an aliphatic hydrocarbon group having 2 to 4 carbon atoms
- R 3 is an alkoxy group
- n is a number between 1 and 50
- m is 1 or 2
- the collector according to the invention can be used alone or in combination with other nitrogen-containing compounds for the flotation of silicate, in particular iron ore or calcite.
- Preferred nitrogen-containing compounds are alkyl ether amines, alkyl ether diamines, alkyl amines or quaternary ammonium salts.
- Another object of the invention is a method for flotation of silicate-containing mineral by bringing the flotation reagent according to the invention with the silicate-containing mineral in contact.
- the invention furthermore relates to a composition comprising 1 to 99% by weight of a silicate flotation collector which is an alkyl ether amine, alkyl ether diamine, alkylamine or quaternary ammonium salt and 1 to 99% by weight of a compound of the formula I.
- the ratio of alkyletheramine, alkyletherdiamine, alkylamine or quaternary ammonium salt to the compound of formula I is preferably between 98: 2 and 75:25.
- R 1 is an aliphatic hydrocarbon group. It is further preferred that R 1 comprises 4 to 22, in particular 6 to 20, and especially 8 to 14 carbon atoms. Particularly preferred are 2-ethylhexyl, Isononan-, Isodekan- and Isotridekanreste.
- R 2 is a C 2 H 4 - or a C 3 H 6 -GmPPe.
- R 3 is a C 2 -C 4 -alkoxy group, in particular an ethoxy or propoxy group. R 3 may also stand for a mixed alkoxy group.
- n is a number between 2 and 40.
- n stands for 2.
- a particularly preferred embodiment of the invention is a compound of formula 1, wherein R 1 is an isotridekanrest, R 2 C 3 H 6 , R 3 is C 2 H 4 -O, n is 2 to 10 and m is 2.
- silicate float collectors which are an alkyl ether amine, alkyl ether diamine, alkyl amine or quaternary ammonium salt, and those with A compound of formula I can be used together, it is preferably one or more of the compounds of formulas (II) to (V).
- R 4 is a hydrocarbon group of 1-40, preferably 8 to 32 carbon atoms and R 5 is an aliphatic hydrocarbon group of 2-4 carbon atoms;
- R 6 corresponds to a hydrocarbon group of 1-40, preferably 8 to 32 carbon atoms
- R 7 and R 8 correspond to one or more aliphatic hydrocarbon group having 2 to 4 carbon atoms
- R 9 , R 10 , R 11 and R 12 correspond to one or more hydrocarbon groups of 1 to 22 carbon atoms and A " corresponds to a suitable anion;
- R 13 corresponds to a hydrocarbon group having 1-40, preferably 8 to 32 carbon atoms.
- the use of the flotation reagent according to the invention can also be carried out in combination with foaming agents and pushers, as known from the prior art.
- hydrophilic polysaccharides such as modified starch, carboxymethylcellulose, or gum arabic are added in dosages of 10 to 1000 g / t as a pusher.
- the silicate flotation is preferably carried out at a pH of 7-12, in particular 8-11, which is for example adjusted with sodium hydroxide.
- the following table represents the flotative results of the collector according to the invention in comparison to the standard reagent. Flotation experiments have been carried out on a siliceous iron ore.
- Table 1 Effectiveness of the collector B according to the invention in comparison to the standard collector A.
- the results show a consistently increased percentage application with an approximately constant Fe content by the Flotationsreagenz B according to the invention over the standard collector A.
- the mixture C consisting of 10% of the inventive collector B and 90% of the standard collector A, shows a significantly increased Application to the standard collector A.
- the flotation reagent according to the invention is applicable in a wide pH range, for example 7 to 12, preferably 8 to 11, and is added to the aqueous pulp in a concentration of preferably between 0.001 and 1.0 kg / ton of crude mineral.
