Fine particles have a relatively high surface area, and therefore more reagents are needed for their processing. In addition, the problem of fine particle flotation is mainly due to their low collision and attachment efficiencies with bubbles. Several strategies are proposed in the literature to overcome the problems of fine particle …

The flotation result show that the ash content of clean coal can be reduced to less than 10% and accompanied by more than 80% combustible matter recovery for both the gutter oil and diesel oil. This study demonstrates that the coal flotation process can become cleaner by using gutter oil as green collector.

The aim of this paper is to show results found combining HIC with the modified flotation, 3PC, to recover valuable gold particles present in fresh tailings from copper–gold flotation circuits. Flotation tailings, fresh or damped, are huge in many countries and recovery of these misplaced fine materials might be important economically.

Malachite fines are easily produced in the grinding process, leading to low malachite flotation recovery. Floc-flotation of malachite fines with an octyl hydroxamate and kerosene mixture was studied to improve the flotation recovery, using microflotation, microscopy image observations, contact angle measurements, and Extended …

The flotation process was divided into five stages and continued for 300 s. Five flotation concentrate products were consecutively collected after 30, 60, 120, 180 s, and 300 s, respectively, during the flotation process. Flotation concentrates and tailings were filtered, dried at 80 °C and weighed for ash analysis. 2.2.2.

The flotation recovery of fine particles faces serious challenges due to the lack of kinetic energy required for supporting their radial displacement and attachment with bubbles. Generally, the hydrodynamic resistance and repulsive disjoining pressure successively inhibit the liquid outflow intervening between the bubble and solid surfaces.
