How Particle Size Affects Flotation 911metallurgist
2021-10-15 How Particle Size Affects Flotation. There is a marked particle size effect on both R and K. Table V gives an example of increasingly finer grinds in flotation with a different sulfide ore blend. Within the times of grind indicated, there is a tendency for both the over-all R and K values to increase with finer grind [see also Table III of

2019-11-1 The effect of the presence of mineral particles on the bubble size distribution was also investigated comparing the bubble size in air-water and air-water-ore systems. The presence of ore particles adhered to the bubble surface, prevented bubble coalescence, consequently reducing the bubble size, compared to the air-water system.

Effect of Particle Size and Grinding Time on Gold
The recovery of gold by ore leaching is influenced by the size of the particles and the chemical environment. The effect of particle size on the dissolution of gold is usually studied using mono-size particles as the gold in solution comes from the ore of a unique leached particle size. This paper proposes a method to estimate the gold dissolution as a function of particle size
