    Jul 01, 2020· The micro-flotation experiment showed that sulfonated lignite had an effective depression effect on calcite. FTIR results illustrated that sulfonated lignite was selectively absorbed on the calcite surface and NaOL could still be absorbed on fluorite surface with depressant sulfonated lignite.

    SBC is more likely to adsorb on calcite surface and hinder further adsorption of NaOL. As a result, the floatability of calcite is seriously deteriorated, and scheelite and calcite achieve selective flotation separation. 4. Conclusions. SBC exhibited superior selective depression effect on the calcite.
