Zinc carbonate, white fine amorphous powder, odorless. The main component of smithsonite, formed in secondary mineral weathering or oxidation zones of zinc-bearing deposits, and sometimes substituted carbonate rock bodies may constitute zinc ore. Zinc carbonate is used as a light astringent, formulating calamine, skin protectant, raw material for latex products.
Zinc carbonate is used as a skin protectant in medicine, as a zinc supplement in feed, as a light astringent and latex product in industry, in preparation of calamine lotion, and in the production of rayon and desulfurization in the fertilizer industry.
