TENORM: Copper Mining and Production Wastes Radiation

Ores that contain copper in the U.S. are typically mined in large, openpits. Copper processing facilities are usually loed near mining or extraction sites. Significant waste volumes are associated with copper production. Mine wastes may contain radionuclides due to their natural presence in ores and can be a source of TENORM.

Extraction of Metals. Extraction of Copper.. Copper is sometimes found as native metal.. Copper ores include copper(II) oxide and copper(II) sulfide. Copper(II) oxide can be reduced by reaction with carbon.. Some copper ores may contain only small amounts of copper. These are called low grade ores and have less than 1% copper but they are still used because copper is so valuable.

Why is the extraction of copper from pyrites more

Why is the extraction of copper from pyrites more

The Gibbs free energy of formation (Δ f G) of Cu 2 S is less than that of H 2 S and CS 2.Therefore, H 2 and C cannot reduce Cu 2 S to Cu.. On the other hand, the Gibbs free energy of formation of Cu 2 O is greater than that of CO. Hence, C can reduce Cu 2 O to Cu.. C (s) +Cu 2 O (s) → 2Cu (s) + CO (g). Hence, the extraction of copper from its pyrite ore is difficult than from its oxide ore
