1. It's specially used in transparent rubber products and foaming agent EVA because of its refractive index similar to rubber.
2. Special basic zinc carbonate can be used as a skin protective agent in medical applications.
3. In the industry, it's used as light astringent and latex products, also is compound of calamine lotion. It can be used as main raw material of rayon production, desulfurizing agent in chemical fertilizer industry and catalyst production.
4. In the oil drilling, basic zinc carbonate reacts with H2S to form ZnS which is stable and insoluble, and that the mud slurry performance is not affected after adding basic zinc carbonate into the mud. So it can eliminate the pollution and corrosion of H2S effectively, also can be used as corrosion inhibitor and sulfur removal agent to process H2S in oil and gas wells.
5.as a zinc supplement in feed
