In the latter half of the 19 th century, the mining focus shifted to zinc, a less toxic metal whose ore also contains leadAs mines "played out," many were closed or sold to new operators. By the 1960s, the advent of regulations on air and water pollution raised costs and lead to the cessation of metallic mining in southwest Wisconsin by 1979.

Listed on the NSE and BSE in India, Hindustan Zinc has built a sustainable underground mining business capable of delivering superior performance with operations comprising 5 zinc-lead mines, 1 rock-phosphate mine, 4 hydrometallurgical zinc smelters, 2 lead smelters, 1 pyro metallurgical zinc-lead smelter, and sulphuric acid and captive power ...
The simple presence of the railroad within the Arkansas zinc and lead mining district did not lead to an immediate and ever-increasing production of ore. The amount of finished zinc produced in Arkansas in 1913 was roughly equivalent to that mined in 1907. Because the output of the Rush mills alone accounted for approximately 50 …
The mining of metals occurs all over the world from a variety of mineral deposit types with varying mining and ore processing technologies (Spitz and Trudinger, 2008). Some countries are endowed with major resources of particular metals, such as Chile and Cu, Brazil and niobium (Nb) or South Africa and Au and the platinum group …
The invention of the floatation process in 1924 resulted in a rapid rise in production. The Austinville mill would use the ore to produce lead and zinc concentrates, which were shipped to a Palmerton, Pennsylvania smelting plant where they were converted to zinc metals and lead-containing zinc pigments (NJhistory.pdf).
ZGH Bolesław S.A. is a producer of high-quality zinc and its derivatives.
