Old copper smelter’s smoke stack is demolished in Superior

November 11, 2018

SUPERIOR, Ariz. (AP) — An old copper smelter’s smoke stack in south-central Arizona has been reduced to rubble.

Resolution Copper demolished the nearly 300-foot brick stack in Superior on Saturday morning.

Smoke hasn’t wafted from the top of the stack of the 94-year-old smelter since 1971.

Resolution Copper is developing a much larger mine at the site.

Company officials determined the stack couldn’t be preserved and was dangerous for workers.

They say the structure also was heavily contaminated with arsenic and other remnants from smelting copper.

Magma Copper Co. began mining the site in 1911 and the smelter opened in 1924 and melted copper from ore for almost five decades.
