Flotation process of micro-fine minerals have historically been hampered by slow flotation
rate, poor selectivity, high reagent consumption, and low recovery. These disadvantages are …

In the past few decades, microbubble flotation has been widely studied in the separation
and beneficiation of fine minerals. Compared with conventional flotation, microbubble …

Froth flotation is often used for fine-particle separation, but its process efficiency rapidly
decreases with decreasing particle size. The efficient separation of ultrafine particles (UFPs) …

As is well known to mineral processing scientists and engineers, fine and ultrafine particles
are difficult to float mainly due to the low bubble-particle collision efficiencies. Though many …

The decreasing size of minerals that need to be separated with flotation technique has
posed a rigorous challenge to conventional flotation techniques. It's urgent for the …

Bulk micro-nano-bubbles (BMNBs) have been proven to be effective at improving the
flotation recovery and kinetics of fine-grained minerals. However, there is currently no …

Flotation in the mining industry is a very significant separation technique. It is known that fine
and ultra-fine particles are difficult to float, leading to losses of valuable minerals, mainly due …

Traditional froth flotation is the primary method for the separation and upgrading of fine
mineral particles. However, it is still difficult for micro-fine and low-quality minerals to …

The froth flotation technique can be considered one of the most efficient methods for the
separation of minerals. Prior to utilizing any physicochemical separation method, the size of …

Rougher column flotation pilot plant (80 kg h− 1 of solids) studies, recovering pyrochlore
(fine and ultrafine samples), compared separation parameters with and without the injection …
