- flotation process preparation
Flotation is the process of separation of beneficial minerals from a mixture by creating froth on which minerals separate out. This is a method of mineral processing in which different minerals are separated selectively. The ores containing multiple metals, such as lead, copper and zinc, can be selectively extracted by using froth floatation.

Froth flotation is a concentration process that selectively separates minerals based on their relationship with water and density. It is widely accepted over other separation methods like magnetic separation and gravity separation. The froth flotation method is dependent on the flotation reagents and not on the properties of minerals.

The flotation method of concentration, used extensively for other metal ores, has only recently been utilized for hematite iron ores. It can be applied as either the sole concentration process or as a final concentration stage to ensure a high-grade product. In the flotation process, air is bubbled through a suspension of fine iron ore in water

Based on the above-proposed studies, the efficiency of the flotation process in the existing preparation plants may probably be minimized. Unfortunately, no such attempts have been made at the pilot-scale level, and this needs to be incorporated. Conducting further studies focused on bio-surfactants mixed with surfactants or bio …

The flotation separation process mainly includes: (1) Grind the ore finely by the ball mill or rod mill to dissociate useful minerals from gangue minerals. (2) Separate the ore by the flotation machine. Adjust the ore pulp and add flotation reagents. (3) Do the flotation processing. (4) Filter, concentrate or dry the product .

For 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). The primary environmental ...
