But in 1875, a contactprocess acid plant was started up at Freiberg in Germany, using leadchamber sulfuric acid decomposed by heat as a source for pure sulfur dioxide. From the mid1880s on, the output of acid produced by the contact process grew rapidly. By then, gases from pyrites had replaced sulfuric acid as a source of sulfur dioxide.
