Definitions
- oleic acid is obtained, for example, from new cultivated rape oil (oleic acid content> 60% by weight) or beef tallow.
- the sulfonation products and their salts derived therefrom are also known substances. According to the process of German patent application DE-A-3.936.001 , the products can be obtained , for example, by reacting unsaturated fatty acid glycerol esters with sulfur trioxide and subsequent neutralization.
- the sulfonation products are complex mixtures which can contain triglyceride sulfonates, partial glyceride sulfonates, partial glyceride sulfates, sulfonated fatty acids, fatty acids and glycerin.
- the properties of the sulfonation products are significantly influenced by the amount of sulfur trioxide taken up in the sulfonation.
- the method according to the invention allows the use of the detergent mixtures as collectors for the extraction of minerals from non-sulfidic ores by flotation alone or in the presence of further anionic and / or nonionic surfactants.
- Suitable alkyl sulfates are the water-soluble salts of sulfuric acid semiesters of fatty alcohols of the formula (IV) R6-O-SO3Z (IV) in which R6 represents a linear or branched alkyl radical having 8 to 22, preferably 12 to 18 carbon atoms and Z represents an alkali metal or an ammonium radical.
- Suitable fatty alcohol polyglycol ethers are addition products of an average of n moles of ethylene and / or propylene oxide onto fatty alcohols, which follow the formula (XIV) in which R17 represents a linear or branched alkyl radical having 8 to 22, preferably 12 to 18 carbon atoms, R8 represents hydrogen or a methyl group and n represents numbers from 1 to 30, preferably 2 to 15.
- Suitable fatty amine polyglycol ethers are addition products of an average of n moles of ethylene and / or propylene oxide onto fatty amines which follow the formula (XVIII) in which R21 represents an alkyl radical having 6 to 22 carbon atoms and R8 and n have the meanings given above.
- Flotation of iron ore A magnetically enriched iron ore of the magnetite type with the following composition, based on the main components, was used as the flotation task: Magnetite approx. 96% by weight Apatite approx. 1% by weight Silicates approx. 3% by weight
