Definitions
- the present invention relates to the use of alkyltriamines in the flotation of silicate-containing minerals and ores.
- Calcium carbonate is purified from silicate-containing and color-providing minerals with the aid of quaternary ammonium salts based on fatty acids or fatty alkylimidazoline compounds. Since calcium carbonate is used in addition to kaolin, rutile and talc as a white pigment in paper and plastic production, the highest possible whiteness or a low concentration of coloring minerals is desired. Due to the hardness of silicate, this would also lead to increased wear on the calenders of paper machines in papermaking. Therefore, calcium carbonate is purified in addition to dry processing via the flotation process.
- silicate content which in the case of calcium carbonate is often characterized as an acid-insoluble constituent, below 1.0% by weight.
- the content of silicate in the task can vary and in some cases be from 10 to 20% by weight.
- fatty amines, alkyl ether amines, alkyl ether diamines or quaternary ammonium salt compounds are used as silicate collectors. These are also 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 4,319,987. The reason for this is the better solubility of the partially neutralized amine functions.
- U.S. 5,540,336 illustrates the synergistic effect of ether amines and anionic collectors for iron ore floatation.
- US Pat. No. 6,076,682 describes the combined use of alkylethermonoamine with alkyletherdiamine for the silicate flotation of iron ore.
- WO-A-00/62937 discloses the use of quaternary amines for flotation of iron ore.
- the object of the present invention was therefore to provide an improved collector for the silicate flotation, which can be used in particular in the reverse flotation but also in the direct flotation.
- the collectors used today for the flotation of silicate-containing minerals have relatively high specific amounts used, which can lead to environmental problems with regard to the residual content of amine in the concentrate or in the mountains. It is known that amines and amine derivatives have high aqua and environmental toxicity. Therefore, one strives to minimize their specific amounts. Furthermore, their residual concentration in the final product should be kept as low as possible.
- alkyl dipropylene triamines leads to a marked improvement in the flotation of silicate-containing minerals compared to the known flotation reagents, it being possible to significantly reduce the specific amounts used.
- the invention thus relates to the use of a compound of the formula 1 RN- [A-NH 2 J 2 (1)
- R is a linear or branched alkyl group or alkenyl group having 6 to 20 carbon atoms and A is a C 2 - to C 4 alkylene group, as a collector in the silicate flotation.
- Another object of the invention is a method for flotation of silicate mineral by bringing a compound of formula 1 with the silicate-containing mineral in contact.
- Another object of the invention is a composition containing 1 to 99 wt .-% of a collector for silicate flotation, which is an alkyl ether, alkyletherdiamine, alkylamine or quaternary ammonium salt, and 1 to 99 wt .-% of a compound of formula 1.
- the compound of formula 1 is also referred to below as a collector according to the invention.
- 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, phosphate or calcium carbonate.
- Preferred nitrogen-containing compounds are alkyl ether amines, alkyl ether diamines, alkyl amines or quaternary ammonium salts.
- the ratio of alkyl ether amine, alkyl ether diamine, alkyl amine or quaternary ammonium salt to compound of the formula is preferably between 95: 5 and 50:50 by weight.
- R is a linear or branched hydrocarbon group. It is further preferred that R comprises 8 to 18 carbon atoms. Particularly preferred are 2-ethylhexyl, Isononan-, Isodekan- and Isotridekan- and Dodekanreste.
- A is either an ethylene - (- C2H 4 -), a propylene - (- C 3 H 6 -) or a butylene group (-C 4 H 8 -).
- A is a propylene group.
- the silicate flotation collectors which are an alkyl ether amine, alkyl ether diamine, alkyl amine or quaternary ammonium salt, and which may be used together with a compound of formula 1, are preferably one or more of the compounds of formulas (II) to (V) ).
- R 4 is a hydrocarbon group having 1 to 40, preferably 8 to 32 carbon atoms
- R 5 and R 6 are one or more aliphatic hydrocarbon group having 2 to 4 carbon atoms
- R 7 , R 8 , R 9 and R 10 correspond to one or more hydrocarbon groups of 1 to 22 carbon atoms and B- corresponds to a suitable anion;
- R 11 corresponds to a hydrocarbon group having 1 to 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, for example, modified starch, carboxymethylcellulose or gum arabic in dosages of from 10 to 1000 g / t as a pusher.
- the silicate flotation is preferably carried out at a pH of 7 to 12, in particular 8 to 11, which is set, for example, with sodium hydroxide.
- the use according to the invention can be carried out both in direct and in reverse silicate flotation.
- the use according to the invention is also suitable for freeing silicate sand from impurities by adding the Silicate sand separates from the impurities using the compound of formula 1 flotation.
- Table 1 presents the flotative results of the collector B according to the invention in comparison to the standard reagent A.
- the flotation experiments were carried out on a silicate-containing calcium carbonate, the acid-insoluble constituents in the task accounting for 14.9%.
- the reagent according to the invention in Example 6 already at a low dosage of only 121 g / t shows a significantly lower proportion of acid-insoluble constituents in the purified concentrate, which the standard reagent only reaches above 400 g / t. Analog behaves that reagent according to the invention in terms of whiteness. This is already at the low dosage 92.0, which is achieved with the standard reagent only with three to four times the amount used.
- Table 2 Effectiveness of a mixture of the collector B according to the invention and the standard collector A.
- Examples 7 to 10 represent mixtures containing 10% of the collector B according to the invention and 90% of the standard collector A.
- Examples 11 to 16 show mixtures containing about 29% of the collector B according to the invention and about 71% of the standard collector A, represents.
- the flotation reagent according to the invention is applicable in a wide pH range, for example 6 to 12, preferably 6 to 8 and becomes the aqueous Cloudy added in a concentration between preferably 0.001 and 1, 0 kg / ton of crude mineral.
