Flotation tests were carried out for a low-grade complex copper ore from Hubei province. The influences of grinding fineness, reagent type and dosage on flotation indices were investigated. A closed-circuit flotation flowsheet consisting of one stage of roughing, three stages of cleaning and three stages of scavenging was adopted to process this kind of ore with Cu grade of feed ore of 0.42%, grinding fineness of -0.074 mm 75.2%, butyl xanthate combined with Z-200 and sodium diethyldithiocarbamate as collectors, calcium hypochlorite combined with lime as regulator. As a result, a copper concentrate with Cu grade of 12.15% and recovery of 85.05% was recovered.
