The copper oxide ore is high oxidation ratio and the high combination ratio with a low grade of Cu 0.71%. Copper concentrate of Cu 15.02% with a recovery of 38.55% was obtained by flotation. The optimum acid leaching conditions were investigated. Effects of lixiviant concentration, solid-to-liquid ratio, leaching time were investigated. The acid leaching efficiency was 78.75% relative to flotation tailings.
Keywords:copper oxide ore; high combination ratio; flotation; acid leaching
