Leaching of fluorides from fly ash has been studied at different conditions (ash/water distilled ratios, variable temperature and for one interval of the very precise pH). The contents of the trace elements in the washed waters have also been evaluated. In this study, we demonstrated that the leaching depends on temperature and pH. To ambient temperature (22°C) and to pH greater than 4.5, one has less leaching of F - and of trace metals. For acidic pH (pH <2.5), the fluoride content is influenced by complexation with Fe 3+ and Al 3+ . This survey showed that the calcium is combined with carbonates and the major
