•Hematite and quartz surfaces with different roughness were conditioned with starch and DDA.•Snap-in force of water droplets on the surfaces of the conditioned minerals was measured.•The largest variation in snap-in force was presented on the roughest surface.•Increasing roughness could enlarge the...
