Abstract
Froth flotation collectors comprising dithiocarbamates of the Formula (I) as described herein are useful for the beneficiation and recovery of metals from mineral ores.
Claims32
A method of beneficiating a mineral ore, comprising:
- forming a slurry comprising mineral ore particles;
- and
- intermixing the slurry with an effective amount of a collector composition comprising a dithiocarbamate compound according to Formula (I):
- wherein each of R and R1 is independently chosen from a member selected from the group consisting of an optionally substituted C1-20 alkyl, an optionally substituted C6-20 aryl, an optionally substituted C2-20 alkenyl, and an optionally substituted C7-20 aralkyl,
- thereby forming a froth comprising a plurality of beneficiated minerals.
