The second term on the right hand size represents the change in particle size due to reaction. This is made up of particles entering size class l due to shrinkage as well as particles leaving size class l due to shrinkage. The term 229; 225;( 223;) indicates that the reaction rate is dependent on particle size.

US20030231995A1 Use of ozone to increase the flotation

The use of ozone during certain stages of metal separation by flotation degrades certain collectors that are absorbed on the particle surface, as well as the collectors and frothers in the liquid slurry. As a result, the mineral particle has a fresh surface and new chemical reagent(s) can be added in the subsequent flotation step(s). Also since ozone oxidizes the iron sulfide particles faster

The slurry that remains after this process has a very fine particle size. Typically, 80% of the ore particles are less than 70 microns in size (about the same consistency as fine beach sand). Such a fine particle size is required for gold liberation the size required for the cyanide to be able to see the gold in the leaching process.

Factors Influencing Copper Ore Flotation Xinhai

Particle size is crucial to copper flotation process index, which is tested in the mining process test report. Flotation particle size must be less than the biggest flotation particle size. Meanwhile, fine particle size will be bad for flotation index for increasing grinding energy cost and mudding slurry.
