  • TENORM Copper Mining and Production Wastes Radiation

    There are two main leaching methods heap leaching and in situ leaching. Heap leaching is the most common method used in the U.S. When processing copper through heap leaching, vast quantities of ore and overburden overburdenSoil and rocks that have been moved out of the way to get to ore are called quot;overburden.quot; In areas where there are high

  • Heap leaching

    The final product is cathode copper. Nickel ores. This method is an acid heap leaching method like that of the copper method in that it utilises sulfuric acid instead of cyanide solution to dissolve the target minerals from crushed ore. The amount of sulfuric acid required is much higher than for copper ores, as high as 1,000 kg of acid per tonne of ore, but 500 kg is more common.

  • COPPER(II) EXTRACTION FROM AMMONIA LEACH SOLUTION

    Ammonia leaching of sulfide copper concentrates generate buffer type liquors (pH ranges from 9 to 10), because of the excess of ammonia and significant amount of ammonia sulfate as a leaching agent. Metals such as Cu, Ni, Co and Zn occur in ammonia systems as a cationic amminacomplexes. Alkalinity of the solution and free

  • Bioleaching an overview ScienceDirect Topics

    To increase copper recovery from chalcopyrite containing flotation concentrates at moderate temperatures, it has been shown that control of redox potentials is mandatory. Through redox potential control, copper leaching rates from chalcopyritepyrite containing concentrates can be significantly enhanced using moderate thermophiles at 45176;C.

    Copper is very well suited to being recycled because it can be remelted endlessly with no loss of properties. For example, old copper plumbing pipes, taps and car radiators are a major source of recycled copper. They can all be melted down and made into new products. Even the few grams of copper in your mobile phone is worth recovering.
