Amine mining collectors
View Patent ↗A family of amine mining collectors that uses alkoxylates allows for the easy adjustment of solubility and molecular weight useful because anionic and cationic mineral collectors require such varying degrees of solubility and molecular weight. The family of the present invention allows for the optimization of both parameters and an increase in collector efficiency.
1. The mining collector of the following structure:
R is linear or branched, saturated or unsaturated, cyclic or acyclic alkyl group from 1 to 9 carbons, R 1 is chosen from —CH 3 , or —CH 2 CH 3 ; n is an integer greater than one.
2. The mining collector of claim 1 wherein R=—C(CH 3 ) 3 , R 1 =—CH3 and n=3.
3. The amine collector of claim 1 wherein R=—CH(CH2) 2 , R 1 =—CH 3 , and n=3.
4. The amine collector of claim 1 wherein R=—CH 3 , R 1 =—CH 2 CH 3 , and n=3.
5. The mining collector of the following structure:
R is linear or branched, saturated or unsaturated, cyclic or acyclic alkyl group from 1 to 8 carbons, R 1 is chosen from —H, —CH 3 , or —CH 2 CH 3 ; n is an integer greater than zero.
6. The mining collector of claim 5 wherein R=—C(CH 3 ) 3 , R 1 =—CH3 and n=3.
7. The amine collector of claim 5 wherein R=—CH(CH2) 2 , R 1 =—CH 3 , and n=3.
8. The amine collector of claim 5 wherein R=—CH 3 , R 1 =—CH 3 , and n=3.
9. The surfactant of the following structure:
Where R is linear or branched, saturated or unsaturated, cyclic or acyclic alkyl group from 1 to 8 carbons, R 1 is chosen from —CH 3 , or —CH 2 CH 3 ; n is an integer greater than zero.
10. The surfactant of claim 9 wherein ═—C(CH 3 ) 3 , R 1 =—CH3 and n=3.
11. The amine collector of claim 9 wherein R=—CH(CH2) 2 , R 1 =—CH 3 , and n=3.
12. The amine collector of claim 9 wherein R=—CH 3 , R 1 =—CH 3 , and n=3.
