Zinc mining in the United States
In 2019 zinc was mined in six States at 15 mines operated by five companies. In 2019, 552,400 tonnes of zinc, 71 percent of US mined zinc production, and 4.2 percent of world zinc production, came from Teck Resources' Red Dog mine, the world's most productive zinc mine, in northwest Alaska, near Kotzebue. The mine opened in 1989. The zinc is shipped as concentrate to foreign smelters. The Red Dog is a polymetallic deposit, which also produces lead and silver Read this article.

In the United States, copper mining has been a major industry since the rise of the northern Michigan copper district in the 1840s. In 2017, the US The Rosh Pinah deposit is one of the largest and most important lead and zinc deposits in the world, having been discovered in 1963. It is located about 15km north of the Orange River and 50km east of the Atlantic coast in Rosh Pinah in the IlKaras Region of southern Namibia (Seke, 2005).

Zinc Ore an overview ScienceDirect Topics
Zinc ores normally contain 5–15% zinc. Approximately 80% of zinc mines are underground mined, 8% are mined from open pits, and the remainder are a combination of both ores ( Ray et al., 2014 ). Zinc concentrate, which contains approximately 55% zinc, is roasted at a temperature approximately 800°C (1472°F).DATABASE OF SIGNIFICANT DEPOSITS OF GOLD, SILVER, COPPER, LEAD, AND ZINC IN THE UNITED STATES PART A: DATABASE DESCRIPTION AND ANALYSIS by Keith R.
