How Hydrometallurgy and the SX/EW Process Made Copper the ,, A schematic diagram of the conventional process for the production of copper and the SX/EW process can be seen here Conventional Copper Extraction Conventionally, copper is recovered by a pyrometallurgical process known as smelting In this process copper ore is mined, crushed, ground, concentrated, smelted and refinedCopper Mining and Extraction: Oxide Ores, The process used to treat sulfide copper ores begins at the mine site, where the copper-bearing minerals are physically separated from the rest of the rock The flow diagram below shows how the percentage of copper increases as the ore is refined, first physically by froth flotation, then chemically by smelting and finally electrolytic refiningRECOVERY OF COPPER FROM OXIDE COPPER ORE BY ,, RECOVERY OF COPPER FROM OXIDE COPPER ORE BY FLOTATION AND LEACHING Kiraz, Emirhan MS, Department of Mining Engineering Supervisor: Prof Dr Mustafa Ümit Atalay December 2014, 65 pages The aim of this study was the recovery of copper from the oxide copper ore by froth flotation and agitating sulphuric acid (H 2 SO 4) leachingMineral Processing, Flotation Our specialists have a comprehensive range of skills in flotation circuits Our extensive experience incorporates all types of conventional, column, and novel flotation equipment This covers a diverse range of projects with concentrators operating at 240,000 tpd or more, involving a full range of base and precious metals and mineralsA Review on Novel Techniques for Chalcopyrite Ore Processing, The different concentrates obtained through differential flotation in pyrometallurgy are usually of poor quality with low metal recovery This further makes pyrometallurgical processing of chalcopyrite very difficult and costly and rendered them difficult to commercialize.
