ادامه مطلبFor instance, the flotation process is performed with water containing 25–35% wt solid ratio and is consumed 1.9–3 m 3 water per ton of ore processed (Gunson et al., 2012; Li et al., 2019). However, the tailing slurry containing roughly 40–60% solids is discharged as a result of the process (Bleiwas, 2012 ).
ادامه مطلبIn the liposome co-flotation assay, the membrane-binding proteins float with liposomes in a sucrose gradient during centrifugation. Taken together, in vitro liposome co-sedimentation and co-flotation assays are useful tools to identify membrane-binding proteins and to provide mechanistic insights into these interactions.
