Fine metals recovery has historically been quite difficult to achieve Hazell notes. Treating finer particle sizes in parallel circuits, increasing particle velocity and reducing the bubble size are all known to have associated challenges and are often ineffective in achieving similar results to ProFlote.

It is noted that in the fractions of fine particles (<20 microns) the recovery falls to values below 50%.1. Figure 1 shows the influence of the particle size Copper recovery.mu. Morris.m). with fine particles (<10 microns) or coarse particles (> 250 . Copper Flotation is no stranger to this phenomenon. the same is mentioned by Jameson (2013).

flotation recovery and efficiency deteriorate rapidly when operating in the extremely fine (<10 μm) or coarse particle size ranges (>250 μm). For minerals such as phosphate, the existing conventional flotation practices are optimal only for the recovery of particles in the size range of about 45 to 250 μm. The improved flotation performance of coarse and …

Carrier Flotation of Fine Particles Carrier flotation can be achieved via the enhanced aggregation between fine (carried) and coarse (carrier) particles under intense agitation and follow by froth flotation. The common and critical requirements for carrier flotation are: 1. presence of coarse particles 2.

In this study, the flotation results for fine, medium, and coarse coal particles and ternary-particle mixtures were analyzed in terms of the modified first-order flotation rate constant. The interaction degree among fine, medium, and coarse particle fractions was evaluated by a developed method according to the flotation results of ternary-particle mixtures.

See Figure 2. This practice allows the advantages of coarse flotation to apply to the whole ore, followed by the advantages of fine flotation to its valuable part. At the same time the disadvantages of fine flotation are restricted to a small part of the bulk of the ore, with the marked advantage of lower costs due to coarse flotation.

Generally in these small plants the recovery of molybdenum is disregarded unless it is present in considerable amounts. Larger plants generally will incorporate a circuit for molybdenum recovery from the copper concentrate by flotation. “Sub- A” Flotation is standard for this service.

Copper recovery of fine particles decreases softly for particles finer than 25 µm. On the contrary, copper recovery of particles coarser than 75 µm reduces dramatically. Sudden reduction in the flotation recovery of these particles is suggested to be due to either lack of liberation of minerals and/or diminishing in ability of bubbles to lift up the coarse particles.

Size by size copper recovery. The main aim of this study is to investigate the recovery of coarse particles in the froth phase. Accordingly, the recovery and grade of copper were evaluated on a size-by-size basis. The samples (concentrate, coarse and fine feeds, dropback and tailings) of each test were screened and each size fraction was assayed.

In any case, the large difference in copper recovery between the grinding environments on an unsized basis noted in Fig. 6 was due to the large difference in fine copper recovery, and that high collector additions did not increase fine copper recovery at all.

The development of froth flotation has improved the recovery of valuable minerals, such as copper- and lead-bearing minerals. Along with mechanized mining, it has allowed the economic recovery of valuable metals from much lower grade ore than previously.
