Abstract
The presently claimed invention relates to a process for the beneficiation of coal and other hydrophobic materials, wherein a collector composition comprising by-products obtained by hydroformylation of octene isomers as a first component and diesel, kerosene and/or C8-C20 olefins as a second component is used.
Claims15
A method for the beneficiation of at least one material, the method comprising:
- a) providing a slurry comprising the at least one material dispersed in a liquid,
- b) contacting the slurry with a collector composition,
- c) subjecting the at least one material to beneficiation to result in a beneficiated material, and
- c) recovering the beneficiated material,
- wherein the collector composition comprises a mixture of collector A and collector B;
- wherein the collector A are by-products obtained by hydroformylation of octene isomers and the collector B is selected from the group consisting of diesel, kerosene and C8-C20 olefins;
- wherein the by-products obtained by hydroformylation of octene isomers comprise
- ≥10 wt. % to ≤20 wt. % isomers of dinonyl ether,
- ≥20 wt. % to ≤35 wt. % isomers of nonyl esters and
- ≥25 wt. % to ≤45 wt. % isomers of trinonyl esters and trinonyl ethers.
A composition comprising at least one target material, a collector composition and a liquid, wherein the collector composition comprises a mixture of collector A and collector B;
- wherein the collector A are by-products obtained by hydroformulation of octene isomers and the collector B is selected from the group consisting of diesel, kerosene and C8-C20 olefins;
- wherein the by-products obtained by hydroformylation of octene isomers comprise
- ≥10 wt. % to ≤20 wt. % isomers of dinonyl ether,
- ≥20 wt. % to ≤35 wt. % isomers of nonyl esters and
- ≥25 wt. % to ≤45 wt. % isomers of trinonyl esters and trinonyl ethers.
