Copper Ore Processing Methods

2017-4-11  Copper Ore Processing Methods. The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore ...

2015-10-9  The copper ore enrichment process is a mechanical process of recovering ore before it undergoes smelting. It is composed of four main stages: mined ore crushing, milling, flotation and drying. The crushing process prepares fresh ore (1.3 % of pure copper) from copper mine to milling process. At this stage, ore is screened on two main fractions ...

Copper Refining - an overview ScienceDirect Topics

In the electrolytic process, copper is electrodeposed to obtain a spongy powder deposit at the cathode rather than a smooth, adherent one. In this feature, it differs from the process of copper refining where a strongly adherent product is desired. Low copper ion concentration and high acid content in the electrolyte favor formation of powder deposits.
