Sažetak
Froth flotation is a process for separation fine solids based on differences of surface characteristics of mineral particles. Separation by flotation is a result of interaction of many variables. The recovery and selectivity depends not only on chemical variables, but also on hydrodynamics of flotation. Hydrodynamics condition in mechanical flotation cell is more turbulent than in flotation column. The paper present results obtained during initial breaking-in of laboratory flotation column on fine coal samples. Optimal dosage value of AF2 collector used in testing was approximately 700 g/t. The best results were obtained by pulp density in range from 50 to 100 g/l. Also, aeration rate should be in range from 24 to 30 l/h. Test with different bubbles sizes showed better result with smaller bubbles.
