A different order of effectiveness was observed for talc depression in the mixed mineral system (CM Dextrin ≥ MP Dextrin > Dextrin TYM). Competition between the valuable and gangue mineral phases for the uptake of MP Dextrin is responsible for its observed decrease in efficiency in mixed mineral flotation.

Hence, to prevent pyrite flotation with dextrin in the presence of xanthates a condition needed is to have a high amount of ferric hydroxide on the pyrite surface to enhance dextrin adsorption. Figure 14 shows the floatability of pyrite oxidized for 30 min and 24 hs as a function of dextrin concentration using 1x10-3 mol/dm3 of ethyl and propyl ...

Dextrin is also usually used as a depressant in coal reverse flotation, during which process coal is depressed and gangue mineral is floated. 1,8−10 In the complex pulp system of coal reverse flotation process, the co-adsorption of dextrin on minerals would affect the performance of reverse flotation. Therefore, it is very necessary to study the …

Fluorite (calcium fluoride—CaF2), also known as fluorspar, is an industrial mineral used in metallurgy, hydrofluoric acid production, and ceramics manufacturing. Based on the results from a previous study, a low-grade fluorspar by-product (20.0% CaF2) originating from the exploitation of a rare earth carbonatite deposit can be …

The results of micro-flotation showed that dextrin had an obvious inhibitory effect on arsenopyrite at this pH and the depression behavior was …

Single-mineral flotation test results indicated that dextrin and starch have comparable depression effect, while dextrin exhibits better selectivity towards specularite than starch. Chlorite's high floatability can be maintained under the same experimental conditions by adding 9 mg/L SHA and there is an effective separation achieved.

Key Differences. Dextrin and maltodextrin, although chemically related, serve different purposes in various applications. Dextrin can be used in adhesives and glues, while maltodextrin often finds its way into food as a thickener or filler, illustrating their versatile usage in various industries. Both carbohydrates, their functions oscillate ...

Abstract The adsorption of both dextrin and xanthate ions at the pyrite/aqueous solution and the galena/aqueous solution interfaces have been studied through batch adsorption tests. Batch flotation tests were also carried out on a chalcopyrite ore and a chalcopyrite-galena scavenger concentrate using dextrin. Dextrin adsorption …

Fig. 3 exhibits the effects of dextrin concentration on the flotation recovery of pyrite and sphalerite in the presence of NaBX as function of pH. As shown in Fig. 3 (a) the recovery of pyrite was found to decrease with the increase of the dextrin concentration at pH= 7, 9, and 10.5. The higher the alkalinity, the more obvious the inhibition effect, and …

The effect of dextrin concentration on the flotation recovery of sphalerite and galena are portrayed in Fig. 11. It is evident from the figure that the flotation recovery of sphalerite remains unaltered at about 97% on addition of different concentrations of dextrin in the range of 0.2–100 ppm at pH 12.1. On the other hand, the flotation ...

The adsorption between dextrin and metal hydroxyl compounds was the main cause of pyrite inhibition, which is attributed to the hydrophilic hydroxyl group in the dextrin molecule. According to these results, dextrin can be used as a selective depressant for pyrite during sphalerite flotation in low alkaline environment.

Alternative processes have been proposed for selective separation of fluorite and gangue minerals (carbonates and silicates) present in fluorspar ores. Calcination and gravity separation processes are methods that have low efficiency and high cost. Flotation is a chemical process that becomes important when high ore grades are required; however, …

Adsorption, electrokinetic and flotation studies have been carried out to investigate the interaction of dextrin with sphalerite and galena.
