Abstract: The performance of xanthogen formates as reagents for the flotation of sulfide copper ores is significantly improved by reacting the xanthogen formate with an aromatic amine. In a preferred embodiment, up to about 20% of an aromatic diamine, most particularly o-phenylene diamine and o-toluene diamine, is used.
