clay promoters in flotation

(PDF) Hydro tropes as promoters in soap flotation

The gangue minerals are clay, marl, detrital quartz. It is observed that all the three promoters show enhanced flotation efficiency compared to flotation with soap-emulsion. Interestingly urea

clay by de sliming is studied at bench scale conducting kinetic and open cycle tests. The phosphate mineral is carbonate apatite of sedimentary origin and the main gangue mineral in the feed to flotation is quartz. The feed and the flotation products are analysed for tri calcium phosphate (TCP, TCP/2.185 = P 2 O 5) and acid insoluble by

PROMOTERS FOR SOAP FLOTATION OF PHOSPHATE MINERALS

Flotation Kinetic studies The results of the experiments from 1 to 4 are given in Table 1 and are also depicted in Figure 1. From the fi gure it is clearly evident that the P 2 O 5 recoveries were much higher when promoters are used. Out of the three promoters tested, urea was found more effective than AOS and LABS. Conventional fl otation tests

Frothers an overview ScienceDirect Topics

The removal of clay slimes (<0.03 mm) is carried out ahead of some flotation circuits to minimize the carryover of this high ash material into the froth product. The ultrafine clay slimes are typically removed using large numbers of small diameter (15 mm or 6 inch) classifying cyclones (Fig. 18).

Amine oxide promoters for froth flotation of mineral ores

Still, a plethora of amine oxide promoters can be easily and efficiently synthesized and have been determined to be effective in the flotation process. The amine oxide promoters suitable for use in the present invention can be represented in conventional fashion by the following general structure: ##STR2## where R 1, R 2, and R 3 are monovalent

The flotation of gold bearing ores — A review

7/1/1994· The order of addition of reagents can also be important and it has been suggested, for example, that when weaker collectors are added first, they adsorb on the strong sites, followed by the stronger adsorbing collector which then adsorbs on the weak sites [45]. Dithiophosphates are probably the most widely used promoters in gold flotation [5,46].

Modeling Catalytic Effects of Clay Mineral Surfaces on

The catalysis of the amide-bond formation for the concerted reaction of acetic acid and methylamine on clay mineral surfaces has been studied by means of density functional theory calculations. Two typical cluster models for surface defects representing hydrogen-bonded interactions (physical defect) and a Lewis acid (chemical) defect have been selected. Additionally, a series of catalysts of
