properties lithopone factory

In addition, with the increasing demand for zinc compounds and lithopone, the continuous exploitation of zinc resources in China, the increasingly poor, fine and complex mineral resources, the comprehensive utilization and environmental protection requirements continue to improve, people have begun to study the recovery of low-zinc raw materials. Use technology. The so-called low-zinc raw materials are mainly low-grade zinc oxide ore, but in addition to low-grade oxidation In addition to zinc in zinc ore, zinc is also present in the acid leaching residue.

A  2023 study published in the journal Environmental Research, scientists examined the effect of titanium dioxide nanoparticles on important gut bacteria in mice. Their results showed “the growth inhibitory effects could be associated with cell membrane damage caused by titanium dioxide nanoparticles to the bacterial strains. Metabolomics analysis showed that TiO2 NPs caused alterations in multiple metabolic pathways of gut bacteria, such as tryptophan and arginine metabolism, which were demonstrated to play crucial roles in regulating gut and host health.” The researchers also found that four different neuroprotective metabolites “were significantly reduced” in urine and in vitro bacteria and vivo urine samples. The researchers concluded: “Increasing evidence implies that the gut microbiome plays a profound role in regulating host metabolism. Our results illustrated that TiO2 NPs hindered the growth of four beneficial gut bacterial strains.”
