Abstract
Conventional starches are chemically crosslinked for use as selective depressants in the flotation of non-sulfide mineral ores. The process employing these crosslinked starches requires lower reagent dosages, exhibits improved selectivity and recovery and exerts a lower load on existing waste treatment facilities. The crosslinking agents employed are bifunctional and are used in sufficient quantities to result in 500 to 10,000 anhydroglucose units per crosslink.
