It can be seen that both recovery and grade of metals (Cu, Ni and Fe) declined with increase in pH. From Figure 5, it can be seen that 84.73% of copper and 30.89% of nickel were recovered as a flotation concentrate at pH 6. Consequently, Cu and Ni grade increased to 1.21 wt% and 0.99 wt% respectively.
