  • TENORM: Copper Mining and Production Wastes Radiation

    Mining and Processing MethodsWaste GenerationDisposal and ReuseEPA and The StatesOres that contain copper in the U.S. are typically mined in large, open-pits. Copper processing facilities are usually located 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. Uranium, which may be co-located with copper ore, may also be recovered as a side stream, if economical. However, in the United States this is not a general pract. Learn more about ur

    SummaryExamples of Current Industrial Bioleaching Operations 1Background of BioleachingMicrobiology of BioleachingLeaching MethodCostsResearchConclusionsApproximately 20% of all copper now produced worldwide is produced by leaching predominantly oxide ores. An undetermined amount of copper is currently recovered from sulfide ores through the aid of naturally occurring microorganisms. If costs can be lowered equivalent to that of the smelting process itself, bioleaching holds promise for the treatment of copper concentrates in situations wherein the capital costs of a smelter are not warranted and/or environmental considerations preclude smelting at that loca

This is used as an adjunct to the SX/EW process in situations where sulfide copper minerals must be leached. Modern commercial application of bacterial leaching began in the 1950s at Kennecott's Bingham mine near Salt Lake City, Utah. It was notd that blue copper-containing solutions were running out of waste piles that contained copper sulfide minerals a condition that shoul

    Until the latter half of the 20th century, smelting sulfide ores was almost the sole means of producing copper metal from mined ores (primary copper production). Davenport, et al, noted in 2002 that even then 80% of global primary copper production was from copper–iron–sulfur minerals and that the vast majority of these were treated by smelting. Copper was initially recovered from sulfide ores by directly smelting the ore in a furnace. The smelters

    All copper sulfides require the presence of Fe 3+ and O 2 as oxidizing agents for leaching to occur. The copper sulfide is oxidized by Fe 3+.The resulting Fe 2+ is reoxidized to Fe 3+ by O 2.The Fe(II)/Fe(III) redox couple acts in a catalytic manner in these reactions (shown for elevated-temperature reaction conditions where the sulfur-containing product is sulfate, rather than the elemental
