DASEN MINING -What Will Influence Mineral Flotation?

Particle Size

Large Particles (>0.1mm): These particles tend to settle quickly, reducing their contact time with reagents. This can negatively impact flotation efficiency.
Small Particles (<0.006mm): These particles can be easily carried over into the tailings, leading to lower mineral recovery.

Slurry Characteristics

Slurry Density: A moderate slurry density is generally optimal. Excessive thickness can hinder aeration, while insufficient density can lead to poor reagent distribution.
Pulp pH: The pH of the slurry significantly influences mineral flotation behavior. Controlling the pulp pH within the optimal range for a specific mineral is crucial for efficient separation.
Flotation Time: The ideal flotation time varies depending on the mineral being floated. Excessive time can result in a lower concentrate grade, while insufficient time can increase tailings grade.
Water Quality: The quality of the water used in flotation can impact the process. Impurities in the water can interfere with reagent action or mineral surfaces.
Pulp Temperature: While flotation typically occurs at room temperature, warming the slurry can sometimes improve results. However, the need for heating should be assessed on a case-by-case basis.

Flotation Reagents

Reagent Selection and Dosing: The choice, quantity, and application method of flotation reagents significantly affect flotation performance. Proper reagent selection and dosing are essential for achieving high recoveries and grades.
In conclusion, understanding the relationship between particle size, slurry characteristics, and flotation reagents is vital for optimizing flotation processes. By carefully controlling these factors, it is possible to achieve high mineral recoveries and concentrate grades.
