The structure of dextrin is similar to that of amylopectin, as shown in Fig. 11, with molecular weights ranging from 800 to 70,000 [85]. Caustic, cationic, and anionic starches are also the products of starch modifications [130]. During starch digestion, the aldehyde groups at the molecular ends of the starch are gradually destroyed to generate ...

Electrokinetic studies have been undertaken to delineate the adsorption mechanism of dextrin onto pyrite.

This figure also shows the zeta potential of dextrin both from this study and after Liu (1988).As noted, dextrin …

Micro-flotation experiments indicated that dextrin selectively depressed calcite at natural pH yet scheelite remained floatable using sodium oleate (NaOL) as a collector. Adsorption density and zeta potential results indicated that dextrin was preferentially adsorbed on the calcite surface and prevented the subsequent NaOL from …

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.

The results of single mineral flotation tests showed that konjac glucomannan had a stronger depression effect on pyrite than traditional organic depressants (Starch, Dextrin, Guar gum) with the ...

The effect of calcium hypochlorite, dextrin and a combination of these reagents on the adsorption behavior of DDTC was investigated corresponding to flotation experiments. Fig. 4 (a) illustrates the adsorption density of DDTC on the surface of pyrite and galena treated by the different Ca(ClO) 2 dosages.

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

These numbers were taken from Fig. 1 at the point where the broken line crosses the line of flotation results at 2500 g/t dextrin. A lack of separation in the Fuerstenau plot corresponds to selectivity index equal to 50/50 while ideal separation to either 0/0 or 100/100. When the selectivity index is between 0/0 and 50/50, there would …

Optimal fluorspar flotation was achieved under the following conditions: 3.6 g/kg of sodium oleate as the collector, 2 g/kg of sodium silicate as the pH modifier and …

A series of flotation experiments have shown that dextrin has an excellent selective depression effect on calcite. According to the FTIR spectra and XPS …

As can be seen from Table II, dextrin decreases the flotation recovery of TABLE II Hallimond tube flotation recovery of molybdenite as a function of the concentration of dextrin at pH 3.8 in 2 10-3 M KCI Amount of dextrin (rag/l) Recovery (%) 0 92 0.2 18 0.83 9 1.67 8 8.3 2 16.7 1.6 50 1.6 100 1.5 26 molyhdenite quite markedly.

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 ...
