For example, Raju et al. (2015) studied the liberation of low-grade barite (82.4 %) tailings interlocked with schistand slate by reverse flotation using amines. It was showed that the use of amines was possible to recover 70 % of barite with 95 % grade in a single stage of column flotation (Bhaskar Raju, 2016).

Step 4 - column flotation. The depression of silicate minerals in the non-magnetic (S5) fraction was carried out using the column flotation (Nguyen et al., 2021a). Firstly, a slurry was prepared by adding the pre-concentrated fluorspar (S5) to water with density of 5% (w.v −1).

construction and design is also simpler. The basic difference between column flotation and mechanical flotation is that column flotation does not have an agitator. Air bubbles in the column flotation are generated from the air flow through the sparger (1). Meanwhile, the mechanical flotation cell mechanism uses an agitator to produce air bubbles.
