Copper mining in Arizona WikiVisually

Copper mining in Arizona, a state of the United States, has been a major industry since the 19th century.In 2007 Arizona was the leading copper-producing state in the US, producing 750 thousand metric tons of copper, worth a record $5.54 billion.Arizona's copper production was 60% of the total for the United States. Copper mining also produces gold and silver as byproducts.

Geochemistry of molybdenum in the continental crust

Alternatively, mantle melts generated during rifting may have assimilated Mo-rich residues in the lower crust or upper mantle to create these Mo enrichments in rift-related magmas. This would imply that significant Mo is removed from evolving magmas in Fe-Ti oxides.

MOLYBDENUM SOLUBILITY IN SILICATE MELT AT HIGH

Hence planetary bulk Mo is expected to be chon-dritic and partitioned solely between silicate crust+mante and metallic core during differentiation. Based on estimates of the Mo content in the silicate Earth [1,2] a partition coefficient for DMo (metal/silicate) = 50-80 would be consistent with equi-librium core-mantle segregation.
