Multiscale Mechanisms of Selective Adsorption of Inorganic and Organic Depressants in Coal-Kaolinite Flotation.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Clay-mineral interference severely limits the flotation of high-ash fine coal, making selective depression essential for improving the ash-recovery balance. Sodium silicate and starch were compared under identical direct-flotation conditions using an original kaolinite-containing high-ash fine-coal sample. Batch flotation, zeta-potential measurements, X-ray photoelectron spectroscopy (XPS), and density functional theory (DFT) calculations were combined to investigate their different interfacial effects. Flotation tests identified 2000 g/t as the dosage providing the best overall separation performance for both reagents. Compared with starch, sodium silicate produced lower clean-coal ash (10.84% vs 11.54%), higher combustible recovery (87.60% vs 84.80%), and a higher flotation perfection index (62.99% vs 59.23%), whereas excessive starch addition caused a marked recovery loss. Zeta- potential measurements showed that sodium silicate caused a pronounced negative shift for kaolinite, whereas starch produced a larger negative shift for coal. XPS further showed that starch markedly increased oxygen-containing carbon species, particularly C-O, on the coal surface, while sodium silicate caused comparatively limited modification. DFT calculations indicated that the starch model fragment (C
