Definitions
- the present invention relates to an improved flotation agent for phosphate ore which, in addition to a fatty acid as collector, comprises a mixture of ethoxylated alkylphenols.
- a dispersant such as, for example, a nonylphenol with 2-5 mol ethylene oxide (EO) and an aliphatic ethoxylated alcohol with the chain length C 11 -C-15, which contains 2-4 moles of EO, is used.
- EO nonylphenol with 2-5 mol ethylene oxide
- a further improvement is obtained if an alcohol with the chain length C 1 -C 15 is dissolved in the dispersant. This alcohol improves the emulsifiability of the dispersant.
- the invention thus relates to a flotation agent for phosphate ore, containing a fatty acid as collector and alkoxylated alkylphenols as dispersants, characterized in that the alkylphenols are composed of a) 8 to 20% by weight of one or more dialkylphenols with alkyl radicals of 8 to 12 C atoms b) 80 to 92% by weight of one or more monoalkylphenols with alkyl radicals of 8 to 12 C atoms,
- Another object of the invention is the use of a mixture of alkoxylated alkylphenols as described above as a dispersant in the flotation of phosphate ores. In a preferred embodiment, it is used with fatty acids as collectors.
- the dispersant preferably comprises 9 to 15, in particular 10 to 13% by weight of component a).
- the content of component b) results from the difference to 100% by weight.
- the alkyl radicals are preferably linear or branched nonyl radicals.
- the ethylene oxide content of constituents a) and b) is between 2 and 4, in particular between 2.5 and 3.5 mol.
- the flotation agent according to the invention contains no alcohols.
- the fatty acid which is the main constituent of the flotation agent according to the invention is preferably a linear or branched monocarboxylic acid having 8 to 26 carbon atoms.
- the fatty acids known as collectors in the prior art can be used for this.
- the flotation agent according to the invention preferably contains between 1 and 30% by weight of the dispersant.
- the flotation agent according to the invention is preferably used in amounts of 100 to 1,000 g / t solids for the flotation of phosphate ores.
- the addition amount of the dispersant according to the invention with separate collector / dispersant metering is preferably between 30 and 150 g / t, in particular between 40 and 60 g / t, based on the solids feed.
- the flotation agent according to the invention can contain, in addition to the fatty acid and dispersant components mentioned, pusher or other components known from the prior art. Such components are, for example, foaming agents and aliphatic polyglycol ethers. In addition, different pushers, such as water glass, can be used separately.
- the flotation agent according to the invention is exemplified below:
- the mixture of mono- and dinonylphenol is produced as follows:
- the reaction can be carried out in such a way that the phenol / nonene mixture is circulated over an acidic fixed bed catalyst.
- the following mixtures were obtained:
- Nonylphenol was ethoxylated in the following steps:
- the calculated amount of ethylene oxide can be replenished. - If the target OH number is reached, the contents of the boiler are cooled to 100 ° C and degassed under vacuum at 100 ° C.
- the dosage can be reduced from 81 g / t to 40 to 60 g / t compared to the reference product, without the concentrate quality or the yield deteriorating.
- composition of the raw ore is Composition of the raw ore:
Landscapes
- Emulsifying, Dispersing, Foam-Producing Or Wetting Agents (AREA)
- Compounds Of Alkaline-Earth Elements, Aluminum Or Rare-Earth Metals (AREA)
- Dental Preparations (AREA)
- Paper (AREA)
- Materials For Medical Uses (AREA)
