    The Recovery of Copper from Smelting Slag by

    2017-2-8  Abstract. Aiming at the recovery of copper from smelting slag, a flotation approach was studied. It was found that this slag composed of fine particles with complex association and distribution, in which bornite was the main copper-bearing mineral after a detailed mineralogy analysis via polarizing microscope, SEM and XRD.

    60 Centuries of Copper: The Flotation Process

    2021-1-21  Only the flotation process mentioned above could make this practicable; and even so, it requires large companies with huge plants, continuous working and immense capital. This explains why, in order to smelt 4 million tons of new copper in 1963, nearly 400 million tons of ore had to be handled and treated in various ways.

    Copper Smelting - an overview ScienceDirect Topics

    Copper smelting plants separate elemental copper from copper concentrates through multiple sulphide oxidizing stages. The considered smelting process includes a continuously functioning flash smelting furnace (FSF) and several Pierce-Smith converters operated in batches. Automating scheduling provides advisory information to operators.

    12.3 Primary Copper Smelting

    2015-9-10  A typical pyrometallurgical copper smelting process, as illustrated in Figure 12.3-1, includes 4 steps: roasting, smelting, concentrating, and fire refining. Ore concentration is roasted to reduce impurities, including sulfur, antimony, arsenic, and lead. The roasted product, calcine, serves as a dried and heated charge for the smelting furnace.

    The Naoshima Smelter has employed the convert er slag flotation method in order to increase reverberatory smelting capacity instead of returning slag to the reverberatory furnace. As the result, we could point out the following advantages; 1) Copper anode produced from copper concentrate was increased 25%, from 3,000T/M to 3,800T/M. 2) Magnetite trouble in the furnace was decreased. 3)
