The raison is that; the efficiency of stibnite froth flotation can be affected by various factors that cause its lost in the tailings. Moreover, as stibnite ore contains clay minerals, this can affect the density of the pulp and lead to overdosing of reagents. This affects the quality of the stibnite froth flotation (Wu et al., 2019).
