Bain adapted from Circular No. 87, July, 2000 For the first time in 10 years, Arizona did not rank first in the Nation in non-fuel mineral production in 1998, falling to third. Arizona's production was $3.0 billion, down $800 million from 1997.

Solution Mining – Mining soluble materials, such as rock salt, potash, and even copper, can be done by introducing a solution through boreholes drilled into the mineral deposit. In the case of rock salt or potash, the solution may simply be water. Solution mining of copper relies on a weak sulfuric or hydrochloric acid to dissolve the copper.

The smelter captures and converts the waste heat from the flash smelting and converting furnaces at the acid plant to generate about two-thirds of its electrical demands. The smelter recovers the heat as a low-pressure steam, which is combined with exhaust steam from the acid plant steam turbine compressors.
