Definitions
- the present invention relates to the use of amine salts in combination with fatty acids as flotation aids in the production of sylvinite, and to a corresponding auxiliary.
- Flotation is used to remove foreign materials, which are usually referred to as slimes or insoluble parts.
- a raw salt pulp is usually first subjected to a scrubbing operation to release the insoluble parts, hereinafter referred to as insoluble parts, and the cleaned raw salt pulp is then conditioned with one or more reagents that promote the removal of the insoluble parts , The conditioned pulp is subjected to a foam preparation, whereby some of the insoluble constituents are removed.
- Flocculants can be used to improve separation.
- an additive blinding agent
- an additive is usually added to the raw salt pulp in order to inactivate residues of the insoluble parts, conditioned with reagents and subjected to the foam preparation for the recovery of sylvinite from other crude potassium salt components.
- DD-B-154 960 discloses a fatty amine for the flotation of potash salts, which is made from natural or synthetic starting substances, almost saturated alkylamines in the ratio of the chain lengths C ⁇ 6 : C ⁇ 8 : C 2 o: C 2 2 such as 10 to 25: 55 to 70: 4 to 10: 5 to 20, preferably 15: 65: 5: 10, and contains a proportion of at least 92% primary amines.
- US Pat. No. 4,045,335 discloses a process for the flotation of langbeinite and kieserite, in which an auxiliary is used which, in addition to a fatty amine, preferably tallow fatty amine, also contains oleic acid or decanedioic acid.
- the object of the present invention was to provide a flotation aid which improves the KCI output in the sylvinite flotation without reducing the concentrate quality.
- the invention thus relates to the use of a mixture of A) at least one compound of the formula
- R 1 is a Cs to C 22 alkyl radical and X "is an anion
- Another object of the invention is a method for flotation of sylvinite, in which the composition described above is added as a collector of the flotation slurry.
- R 1 is a Cs to C 22 alkyl radical and X "is an anion
- Component A of the composition according to the invention preferably comprises a radical R 1 with a chain length of 12 to 20, in particular 16 to 20, especially 18 carbon atoms.
- X can be any anion, but is preferably a chloride, formate or acetate anion.
- a particularly preferred component A is stearylamine acetate.
- Constituent B of the composition according to the invention is preferably a branched carboxylic acid having 14 to 22 carbon atoms, in particular isostearic acid.
- the preferred mixing ratio of A: B is 90:10 to 10:90, in particular 75:25 to 25:75.
- components A and B add up to 100% by weight
- Suitable solvents are glycols, especially butyl polyglycol, the residues from the oxo alcohol synthesis and, if appropriate, water as a secondary component.
- Residues from oxo alcohol synthesis have, for example, the following composition: constituent concentration range (% by weight)
- compositions according to the invention are used in a mixture with quaternary ammonium salts.
- Such salts have the formula [NR 2 R 3 R 4 R 5 ] + X _ , in which R 2 , R 3 , R 4 and R 5 represent alkyl radicals having 1 to 18 carbon atoms.
- R 2 , R 3 , R 4 and R 5 represent alkyl radicals having 1 to 18 carbon atoms.
- One of the radicals R 2 to R 5 is preferably a short-chain radical, for example methyl or ethyl, and the other radicals are long-chain radicals having 8 to 18 carbon atoms. It is also possible to combine 2 short-chain with 2 long-chain residues.
- Suitable anions X are chloride and sulfate.
- compositions according to the invention are mixed with ether propylene amines of the formula R 6 -0- (CH 2 ) 3 -NH 2 and / or ether propylene diamines of the formula
- R 6 -0- (CH 2 ) 3-NH- (CH 2 ) 3-NH 2 is used.
- R 6 here stands for an alkyl group with 8 to 18 carbon atoms.
- ether propylene (di) amines in the form of their salts, in particular chlorides, acetates or formates.
- the composition according to the invention is used for use as a flotation aid in amounts of preferably 10 to 500, in particular 20 to 200 g / t.
- Component A was stearylamine acetate
- component B was isostearic acid.
- the amount used was 40 g / t (t.q.).
- the mixing ratio A: B was
- the crude salt was ground and suspended in a saturated saline solution. After the collector was added, air was forced through the suspension. The salt, which is made hydrophobic by the collector, floats on the surface of the suspension and is skimmed off there. The potassium content of the concentrate thus obtained was determined, as well as its ratio to the total amount of potassium present (application).
