    Fig.3. Copper Slag Copper slag is a by-product formed during the copper smelting process. The countermined copper slag has to be properly treated or washed to meet certain recycling criteria before it can be further used for other applications. The production of one ton Copper generates, approximately 2-3 tons of Copper Slag.

    Cement Kiln Dust WasteCrude Oil and Natural Gas WasteFossil Fuel Combustion WasteMining and Mineral Processing WasteCement kiln dust (CKD) is a fine-grained solid by-product generated during the cement manufacturing process and captured by the facility’s air pollution control system. Because much of the CKD is unreacted raw materials, it is often returned to the production process. CKD that is not returned to the system, typically due to the presence of undesired constituents such as alkali metals, is disposed of in landfills, or sold for beneficial use. Currently, CKD waste is generally excluded from the definition of hazardous wa

  • Iron Recovery from Discarded Copper Slag in a RHF Direct

    That is to say, the copper slag is a kind of costless raw material. Thanks to the rich zinc content in such copper slag, the same can also be recovered in the form of zinc oxide powder when the iron element is recovered. Therefore, copper slag with 40% Fe content is a better iron resource economically than conventional iron deposits. Fe exists
