The process flow diagram is shown in Fig. 12. Firstly, copper is extracted from CSS by flotation method, and then iron is extracted from flotation tailings by microwave fluidization roasting and high-efficiency separation technology, so as to realize the comprehensive recycling of copper and iron.
The studied copper solvent extraction process consists of four units, three for extraction and one for stripping, as presented in Fig. 2.The inputs of the process are pregnant leach solution series and parallel flow rates, F(PLSS) and F(PLSP), pregnant leach solution copper concentration, c(PLS), lean electrolyte flow rate, F(LE), lean electrolyte copper …
Two steps involved in the extraction of copper metal from concentrated copper glance ore are: 1. Roasting: Copper glance, being a sulphide ore, is heated in the presence of air. Copper (I) sulphide is converted to copper (I) oxide. Copper (I) oxide, so formed, reacts with non-oxidised copper (I) sulphide ore in the absence of air to form copper ...

Heating and melting are frequently used to extract copper (Cu) from its parent ores [1,2,3,4].Roasting, smelting, and conversion are the three phases of the heating and melting process for primary copper ores [5,6,7,8,9,10,11].Significant amounts of copper are lost as dust in the first and second phases; this dust is referred to as waste copper dust (WCD).

Great strides have been accomplished in the conventional treatment of copper ores, such as at the Bingham Canyon mines, in Utah and the adjoining copper smelters. A schematic diagram of the conventional process for the production of copper and the SX/EW process can be seen here. Conventional Copper Extraction
flow diagram on copper extraction copper extraction and purification chemguide This page looks at the extraction of copper from its ores, its purification by electrolysis, and some of its uses. flow sheet to extract to process copper ore.
The copper and nickel remain In solution. The copper is solvent extracted. The types of solvent used in this process are organic ones such as oximes, diethyldithiocarbamate, butyl acetates and ketoximes. These solvents form organometallic chelates with the metallic species in question, in this case copper, which are soluble in the organic phase.
