Chemical phases analysis of Barium in Ores by X-ray Fluorescence Spectroscopy.
Article in PloS one, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Accurately determining the phase states of barium carbonate, barium silicate, and barium sulfate in ores. It's crucial for advancing research on barium ore mineralization and improving beneficiation and smelting processes. This study aimed to investigate the integration of phase analysis and X-ray fluorescence spectrometry(XRF) to assess the phases of barium in ores, only requiring simple sample pretreatment before measurement. The acetic acid separation drip method was used for the determination of barium carbonate, while the hydrochloric acid separation drip method was used for barium silicate. Additionally, the fusion sample preparation method was applied for the analysis of barium sulfate. The results were consistent with those obtained using chemical methods, and the precision of the relative standard deviation(RSD) was less than or equal to 2.74%, satisfying the analytical requirements. This study combines chemical separation with XRF for continuous and precise phase determination. This approach enhances applicability of XRF in chemical phase analysis and provides a simpler, more environmentally friendly alternative to traditional techniques. It can be applied to barium phase analysis in general barium ores.
