Zinc oxide, sometimes referred to as zinc white or calamine, is a chemical compound containing zinc in the +2 oxidation state. As a result, it is classified as an amphoteric oxide. Zinc oxide is a generic term for metal oxides that have a variety of uses, including use as a food additive and as a topical emollient in various therapeutic ointments. Because of its outstanding UV-absorbing characteristics, zinc oxide is most commonly used in sunscreen products. Zinc oxide, in concentrations ranging from 10% to 25%, will protect skin from UV rays more efficiently than many other sunscreens that rely solely on titanium dioxide to block those wavelengths. It’s also utilised as a pigment and opacifier in paints and coatings, such as house paint and priming paints.

Manufacturing
The process starts with white seal dross, which is crushed and pulverised in a jaw crusher. Any leftover steel or other ferrous metals are removed from the powder using a magnetic separator. The moisture will be removed using a water spray, a blast of air, or a belt dryer. The remaining particles are dried in an oven or furnace until they are reduced to a safe level. Depending on their level of hydration, this could take anything from a few hours to many days.
