This U.S. Geological Survey (USGS) data release provides the descriptions of the only U.S. sites—including mineral regions, mineral occurrences, and mine features—that have reported production and (or) resources of gallium (Ga). The sites in this data release have contained resource and (or) past production of more than 16 metric tons Ga metal, which was the approximate average annual consumption of Ga in the U.S. from 2016 through 2020. This dataset contains the Round Top deposit in Texas and the Apex deposit in Utah.

Gallium occurs in many different minerals and rocks where substitution takes place with elements of similar size, such as zinc, or similar charge, such as aluminum. Therefore, Ga is primarily recovered as a byproduct of processing aluminum or zinc ores (Foley and others, 2017). Some U.S. zinc deposits contain up to 50 parts per million Ga, but Ga is not currently recovered from U.S. mineral deposits.
