Fine particle flotation results in an extremely inefficient process performance, marked by reduced flotation recovery and affecting the concentrate grade []. Ores become more complicated, disseminated, and consequently more difficult to process because mineral resources have been exploited over time.

Self-magnetization of pyrite and its application in flotation

and the fact that the stronger the magnetism of the magnetized pyrite, the larger the aggregate size, indicates that the agglomeration is somewhat in line with the flotation, also confirming that the MSF is more suitable for fine particles than traditional flotation.

 · Abstract The effects of shear strength on aggregation flotation processes for fine spodumene (particle size less than 19 μm) were investigated in this study. Sodium oleate was used as a surfactant and collector. The shear strength was controlled by varying the agitation speed of a self-made stirring apparatus. The aggregation process was studied by measuring the continuous …

It has been reported that hydrophobic fine particles could aggregate with each other or a large particle to form larger particles, thereby improving the flotation recovery []. The mechanisms of shear-flocculation and carrier flotation are governed by physical, chemical, and geometrical variables, which have been investigated comprehensively in Subrahmanyam''s review paper [ 34 ].

 · These fine particles are very hard to be separated by flotation process in the high-shearing fluid of flotation solution. However, the addition of Fe 3+ and CTAB reagents give the precipitate flocs much larger, looser, coarser and lighter structure characteristics.

The limits of fine and coarse particle flotation.

 · The flotation of mineral sulphides and oxides, for example, operates most efficiently when the particle diameter is between 10 and 150 [micro]m (Shergold, 1984). Coarse and fine particles are often not recovered during the flotation process, or are recovered poorly.

Coarse Phosphate Flotation

 · In a turbulent field, however, the upper grain size limit in flotation is reached when the dynamic stress on the bubble-particle aggregate is larger than the energy required for detachment. According to calculations by Schulze 1984, the upper floatable size limit would be drastically reduced by the turbulent field in a flotation machine to just a fraction of the equivalent value under ...
