Zeta-potential measurements were made to determine the elec. state of phosphor materials on the basis of which a feasibility study can be performed for the use of flotation in the recovery of fine (median size <13 μm) rare earth phosphors from waste fluorescent lamps. Tests were carried out on specimens of white (calcium halo-phosphate), red, green and blue (rare earth) phosphors in a 17:1:1:1 ratio of their mixture, and with actual waste phosphor materials. The effects of a cationic, dodecyl ammonium acetate (DAA), and two anionic, sodium dodecyl sulfate (SDS) and sodium oleate collectors on the floatability of materials, as well as that of Na2SiO3 dispersant on the separation characteristics, were investigated in different pH ranges. The process, applied to actual discarded waste phosphors gave, in a two-stage separation scheme, sink products assaying 17.7-23.8 and 21.5-25.9% rare earth phosphors for DAA and SDS flotation, resp. The recovery and Newton’s efficiency were about 70-90%/0.26-0.37 and 66-82%/0.18-0.20 for DAA and SDS flotation, resp.
