| titleOfInvention | Modified alcohol frothers for froth flotation of sulfide ore |
| abstract | Disclosed is a process for the concentration of sulfide ore wherein an aqueous slurry of sulfide ore particles are subjected to sulfide ore froth flotation under sulfide ore froth flotation conditions. The improvement in process comprises using an effective amount of a frothing agent selected from the group consisting of:n (a) the reaction product of a C 5 -C 10 diol and a C,-C 7 carboxylic acid; (b) the reaction product of a C 5 -C 10 diol and an acrylonitrile; (c) the reaction product of a C 2 -C 4 alkylene oxide and a C,-C 7 carboxylic acid; (d) the reaction group of a C 2 -C 4 alkylene oxide and a C 5 -C 10 diol; (e) the reaction product of a C 2 -C 4 alkylene oxide and an acrylonitrile; and (f) mixtures thereof, nthe resulting modified alcohol frothing agents have at least one hydroxyl group thereon. The modified alcohol frothing i agents of the present invention provide improved flotation kinetics and selectivity in the sulfide ore float. |
