History

The oldest piece is made of Betty, which was obtained in archaeological excavations in Dordosh in the Transylvania region, with a composition of 87.52 percent Zn, 41.11 percent lead and 1.07 percent iron. . In the ruins of Cameros, destroyed 500 BC, a bracelet has been obtained that has been filled. 200 years after the Roman times, the Romans became familiar with rice, shaping it with a melting and rejuvenating method in a furnace and with copper. During this process, zinc oxide was first regenerated. The vapor then penetrated the dermas, and with increasing temperature, the product melted and rice was produced with a uniform composition.
Zinc in the form of zinc oxide from the 12th century was produced in India and later produced and used in the 17th century in China. In about 1730, zinc plating came from China to England, and in 1739, a distillation license was registered, and from 1743 to 1740, a zinc mill with a production of 20 tons per year was constructed in Bristol. In this process, a mixture of carbon and zinc oxide ore was used in a furnace that was embedded in the bottom of the tube and evaporated in the liquid tube and collected outside the furnace.
Originally produced in the United States for the first time in 1835 in Washington. In 1880, zinc hydrometallurgy was commonly used to produce zinc sulfate and to use it to produce Lithapone pigment. By the 1880s, sulfur dioxide was not much noticeable, and in Europe, most of the chalamine was used to produce zinc. However, during the years 1881, the filtration process was modified and SO2 gas was produced at high percentages, and thus sulfur rocks were placed in the circuit of production
