Abstract Sherwood Copper’s Minto Mine processes a high grade copper–gold deposit in Yukon, Canada The ore mined is from a primary copper sulphide deposit with separate additional deposits of copper oxides In conjunction with Ausmelt Chemicals, Minto is currently investigating options to recover copper oxide and sulphide minerals using flotation by blending their primary sulphide ore with From previous ﬂotation investigations of mixed copper oxide and sulphide minerals using xanthate and hydroxamate collectors it was hard to distinguish the impact of the alkyl hydroxamate Flotation of mixed copper oxide and sulphide minerals A different approach was made towards flotation of mixed copper ore using xanthate and hydroxamate as traditional and chelating collector to recover both sulphide and oxide minerals of copper Flotation of mixed copper oxide and sulphide
