gold impact flotation cell with low energy consumption. ... Current practice uses slurry pHs in excess of 10 achieved by adding burnt lime (CaO). ... The flotation experiments were conducted in a 0.5 L micro-flotation cell with the pulp mass ratio of 6 and the impeller speed of 1900 rpm. Kerosene or/and NaOL were used as collector.
