احصل على السعرPart of the fine and useful minerals produced are the minerals associated with gangue body, and froth flotation is carried out to obtain part of the coarse concentrate and waste part of the tailings. Among them, there are some syngene minerals, which need to be regrinding to realize the monomer dissociation, and then enter the froth flotation stage again to separate the useful fine grained
احصل على السعرThe fine mud produced in non sulfurized minerals will not only consume flotation reagents, but also adhere to the surface of coarse particles, interfering with the separation process. Some of the fine mud may also contain a large amount of useful minerals, so sometimes the desilting material is divided into coarse and fine grain grades for separation.

احصل على السعرIn most flotation pulps, a low solid concentration is generally used. The more dilute the pulp, the cleaner the separation [].As can be seen in Figure 3, when the UG2 and Great Dyke feed solid concentration exceeds 25 vol.%, a discernible increase in the apparent viscosity of the feed samples could be detected, which would result in rheological complexities in the separation process.
احصل على السعر(1) Fine valuable minerals adhere to the coarse gangue minerals, which leads to the passive loss of valuable minerals. In hematite (Fe 2 O 3) flotation, for example, fine hematite particles can be adsorbed on the surface of quartz, resulting in a reduction of hematite
