Abstract
A composition for use as a collector, leaching aid, sequestrant or chelant, comprising at least one at least one derivatized carbohydrate surfactant such as an alkyl derivatized polyglycoside, glycolipid, glycerol glycolipid, sphingo glycolipid, sulfolipid, phospholipid, glucoside, rhamnolipid, or sophrolipid.
Claims37
A composition for use as a collector, leaching aid, sequestrant or chelant, comprising one or more of the following:
- a. at least one derivatized carbohydrate selected from an alkyl derivatized polyglycosides, glycolipid, glycerol glycolipid, sphingo glycolipid, sulfolipid, phospholipid, glucoside, rhamnolipid, sophrolipid;
- b. at least one crosspolymer of an alkyl polyglucoside;
- c. at least one derivatized alkyl polyglucoside, and/or an alkyl polyglucoside sorbitan ester crosspolymer;
- d. at least one of the (a)-(d) further combined with more traditional beneficiation reagents such as xanthates, fatty acids, depressants, frothers, pH modifiers.
