Antimony Concentration Plant

The concentration of arsenic and antimony in the north soils were higher than in nonimpacted ones and, in the case of arsenic, greatly exceeded the world average concentration reported for this element in soils. The highest arsenic and antimony concentrations were found in Calama and Quillagua soils, two different sites in the Loa valley.
