Synergistic effects of sulfidization flotation on malachite enrichment: a review.
Review in RSC advances, 2026. 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
Malachite and other copper oxide minerals are important copper resources that support industrial development and national defence. Flotation is the most widely used and effective method for enriching oxidized copper ores, and sulfidization has been increasingly employed to improve flotation performance. This review summarizes the sulfidization pathways on the malachite surface, the formation of reactive sulfide species, the factors influencing sulfidization, and the regulation of surface hydrophobicity. Various analytical techniques are reviewed to elucidate the sulfidization behaviour and morphological evolution of malachite from multiple perspectives. Sulfidization flotation primarily includes sulfidization-xanthate flotation and the combined use of sulfidizing and activation agents, both of which significantly improve flotation performance. The mechanisms by which activation agents enhance sulfidization are also discussed based on the sulfidization process of malachite. In addition, various activation mechanisms are analysed, the activation pathways and products are discussed, and the morphological and chemical changes occurring during sulfidization are described. These insights are crucial for optimizing reagent dosages and identifying optimal treatment conditions to enhance mineral recovery. Therefore, future research on sulfidization technologies for oxidized copper ores should focus on addressing existing knowledge gaps and developing sustainable reagent systems. Such efforts will provide theoretical guidance for improving the flotation performance and industrial utilization of oxidized copper ores.
