Factories specialized in barium sulfate production employ different techniques to refine the mineral. The most common method is the wet process, where barite is ground and mixed with water, allowing lighter impurities to float while the heavier barium sulfate sinks. After separation, the resulting slurry is dried and heated to obtain the final product. Some advanced factories also utilize flotation or magnetic separation methods to enhance purity.

In a review published in 2022 in the journal Archives of Toxicologyresearchers found that the ingestion of E171 is a “a definite health risk for consumers and their progeny.” After reviewing dozens of in vivoex vivo and in vitro studies on the toxicity of E171, the researchers wrote that two facts must be noted: “First, reprotoxicity studies show that animals of both sexes are impacted by the toxicity of these nanoparticles, underlining the importance of conducting in vivo studies using both male and female animals. Second, human exposure begins in utero via maternal-fetal transfer and continues after birth by breastfeeding. Children are then chronically re-exposed due to their food preferences. To be relevant to the human in vivo situation, experimental studies should therefore consider nanoparticle exposure with respect to the age or life period of the studied population.”
