Methyl isobutyl carbinol mixture and methods of using same
The invention is directed towards methods and compositions for separating materials are provided. The present invention provides a method of separating first material from a second material such as mixing the first material and the second material in a slurry with a beneficiation composition. The beneficiation composition can comprise methyl isobutyl carbinol mixture derived from a methyl isobutyl ketone and/or methyl isobutyl carbinol manufacturing process. Additionally air bubbles can be provided in the slurry to form bubble-particle aggregates with the first material and the bubble-particle aggregates can be allowed to be separated from the second material.
1. A method of separating a first material from a second material, the method comprising: mixing the first material and the second material in a slurry with a beneficiation composition, wherein the beneficiation composition comprises an MIBC mixture and the MIBC mixture comprises MIBC, at least one C10 to C18 ketone, 2,6,8-trimethyl-4-nonanone, and one item selected from the list consisting of: 2,6-dimethyl-4-heptanol, 2,6-dimethyl-4-heptanone, 3,3,5-trimethyl-1-1 cyclohexanone, 4,6-dimethyl-2-heptanone, 4,6-dimethyl-2-heptanol, and combinations thereof.
2. The method of claim 1 where air bubbles are provided in the slurry to form bubble-particle aggregates with the first material; and allowing the bubble-particle aggregates to be separated from the second material.
3. The method of claim 2 , wherein the MIBC mixture is blended with one or more components selected from a group consisting of light hydrocarbon oils, petroleum ethers, fatty acids methyl esters, fatty acids, c4-c20 alcohols, c4-c20 aldehydes, c4-c20 esters, phosphate, sulfate, sulfonate, amine salt, xanthates, hydrophobic polymers, and combinations thereof.
4. The method of claim 1 wherein the MIBC mixture comprises about 50 to about 90 weight percent of MIBC.
5. The method of claim 4 wherein the MIBC mixture comprises about 5 to about 25 weight percent of C9 alcohols.
6. The method of claim 4 wherein the MIBC mixture comprises about 5 to about 25 weight percent of C9 ketones.
7. The method of claim 4 wherein the MIBC mixture comprises about 5 to about 50 weight percent of C9 to C18 ketones.
8. The method of claim 4 wherein the MIBC mixture comprises about 5 to about 50 weight percent of C9 to C18 alcohols.
9. The method of claim 1 wherein the beneficiation composition is comprised of a MIBC mixture derived from a MIBK and/or MIBC manufacturing process.
10. The method of claim 9 , wherein the MIBC mixture is blended with one or more components selected from a group consisting of light hydrocarbon oils, petroleum ethers, fatty acid methyl esters, fatty acids, c4-c20 alcohols, c4-c20 aldehydes, c4-c20 esters, phosphate, sulfate, sulfonate, amine salt, xanthates, hydrophobic polymers and combinations thereof.
11. The method of claim 9 , wherein the MIBC mixture comprises about 50 to about 90 weight percent of MIBC.
12. The method of claim 11 , wherein the MIBC mixture comprises about 5 to about 50 weight percent of C9 to C18 alcohols.
13. The method of claim 11 , wherein the MIBC mixture comprises about 5 to about 50 weight percent of C9 to C18 ketones.
14. The method of claim 11 wherein the MIBC mixture comprises about 5 to about 25 weight percent of C9 ketones.
15. The method of claim 11 wherein the MIBC mixture comprises about 5 to about 25 weight percent of C9 alcohols.
