The present work evaluates the reagents and appropriate conditions in order to obtain flotation concentrates with high copper content and low arsenic recovery. The studied ore is a blend of 80 % w/w El Valle ore and 20 % w/w Carlés ore, this latter being rich in copper and arsenic content. Those ores are worked from two deposits located in Asturias-Spain and treated at a concentration plant nearby. The arsenic content in the floated concentrate is penalized by the buyer. The main conclusion from the study is that a dithiophosphate is the collector that provides the best results, what was confirmed at plant-scale.
