Definitions
- the invention relates to the use of the reagents described below as flotation aids.
- Flotation has become established for the sorting of fine-grained contaminated mixtures of coal, ore and other solids.
- the different wettability of different substances is used as a separating feature and reinforced by adding flotation reagents to the solid slurry.
- flotation reagents added to the solid slurry.
- the surfaces of the mineral to be floated are made hydrophobic, so that the air bubbles introduced into the slurry accumulate there, which generally allow the valuable material to float, after which the foam layer loaded with solids on the liquid surface is separated from the remaining solids is subtracted.
- MIBC methyl isobutyl carbinol
- Alcohols and polyglycols, and also petroleum, kerosene or gas oils are used as flotation reagents, but all of them are difficult to biodegrade, so that the use of such reagents is impaired in terms of environmental compatibility.
- the object of the invention is to find reagents for use as flotation aids which are biodegradable and yet are suitable for effectively influencing the surface properties of the solids to be flotatively sorted, in particular when carrying out the flotation.
- Flotation reagents which contain the fatty acid alkyl esters specified in claim 1 or consist of mixtures of such esters have the advantage that they are biodegradable and therefore environmentally compatible.
- the use of mixtures of such flotation reagents which contain 1 to 100% of the fatty acid alkyl ester specified in claim 1 improves the work, storage and transport-related aspects of handling these chemicals.
- the fatty acid alkyl esters contained in the flotation reagent or in the flotation aid are by esterification of fatty acids or transesterification of vegetable oils, e.g. B. rapeseed oil has been produced.
- GO gas oil
- MIBC methyl isobutyl carbinol
- EKOFOL trademark for flotation aids from EKOF Flotation GmbH The three test series compared reagent systems that contain 30% of a non-polar component.
- EKOFOL B 7 30% rapeseed oil methyl ester, 70% alcohols and esters (experiment no. 2);
- EKOFOL 440 30% non-polar fraction from petrochemicals, 70% alcohols and esters (experiment no. 3).
