- W2594072047 abstract "A new process concept has been developed that will enable significant increases in productivity to be achieved from existing copper smelting and converting operations. Key to the Synergistic Copper Process is the utilisation of the excess enthalpy currently available from the sulphide oxidation reactions that take place pyrometallurgical processing. The process involves the preparation of precipitated oxide forms of copper and their introduction of this intermediate product into copper smelting and converting reactors. The precipitated oxide can be prepared using any leaching technology to recover copper ions in aqueous solution. The solution is treated to increase the pH of the solution and produce selective precipitation of firstly iron and then copper. The intermediate copper product can be then be pre-treated utilising low grade waste heat to remove residual free or chemically-bound water before being introduced directly into the pyrometallurgical reactors as a supplemental copper feed source. The process can be used in conjunction with all presently-used pyrometallurgical copper production process technologies. This process route provides an attractive alternative to the SX/EW route currently employed industrially to recover copper from oxidised and some sulphide ores. The process can be adapted to any virtually method of obtaining leach copper. The precipitated intermediate product has grades comparable with conventional sulphide concentrates and can be blended with other copper smelter feedstocks or used directly as a high-copper, low-iron feedstock in the smelting or converting stages. The process enables smelter productivity to be increased with minimal capital expenditure on smelter upgrades; provides an alternative method of preparation and of utilising new copper-containing intermediate products to improve overall copper recovery." @default.
