    Oxide Ores. The copper-bearing solution from the solvent extraction operations is plated into pure copper cathodes using a process called solution exchange electrowinning (SX-EW). Stainless steel blanks are added to the plating tanks to act as cathodes and copper is plated onto them by electro-chemical deposition.

  • Mineral Processing WastesMaterial DescriptionUser

    Some ores such as iron ore are found in relatively high percentages and are fairly easy to separate. Therefore the resultant tailings are coarser than those from other ores such as copper which is found in very low percentages and requires very fine grinding for separation. Hence copper tailings are usually quite fine-grained.

  • 12.3 Primary Copper Smelting

    Mining produces ores with less than 1 percent copper. Concentration is accomplished at the mine sites by crushing grinding and flotation purification resulting in ore with 15 to 35 percent copper. A continuous process called floatation which uses water various flotation chemicals and compressed air separates the ore into fractions.

    To be more specific let us take the example of a copper ore whose grade or copper content is only 1 by weight. Let us assume that the sole copper mineral species in this ore be chalcopyrite which is one of the most popular copper minerals found in copper ores in our planet. The chemical formula of chalcopyrite is known to be CuFeS2.

    The barren rock or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore. By far the greatest proportion of copper is extracted from the sulfides of copper iron and sometimes other metals. Such ores originate from sulfur-bearing volcanic magmas which have separated into metal sulfides and siliceous melts.
