extraction process of copper from chalcopyrite

Relationships between galvanic interaction copper How Hydrometallurgy and the SX/EW Process Made Copper

A moderately thermophilic culture was enriched and adapted to bioleach chalcopyrite at high pulp density In order to further improve copper extraction effects of galvanic interaction on bioleaching performance and community dynamics were investigated by adding pyriteThe copper bearing aqueous phase is advanced to the electrowinning EW stage of the process while the barren organic phase is returned to the extraction stage of the process In the electrowinning stage of the process the copper is reduced electrochemically from copper sulfate in solution to a metallic copper cathode Electrowon copper cathodes are as pure as or purer than electrorefined

Two new process flowsheets have been developed which combine chloride leaching of copper from chalcopyrite with solvent extraction to selectively transfer copper to a conventional sulfate The parts per million copper in solution can be compared directly for estimating the various effects of the factors on copper extraction because the chalcopyrite liquid ratio was maintained constant The effects were estimated by running a multiple linear regression with the linear interactive and second order effects in coded form as the independent variables and the parts per million

The copper II ion in the chalcopyrite is reduced to copper I sulfide which is reduced further to copper metal in the final stag The iron in the chalcopyrite ends up converted into an iron II silicate slag which is removed Most of the sulfur in the chalcopyrite turns to sulfur dioxide gas This is used to make sulfuric acid via the contact process copper extraction and purification Getting copper from chalcopyrite CuFeS 2 Chalcopyrite also known as copper pyrites and similar sulphide ores are the commonest ores of copper The ores typically contain low percentages of copper and have to be concentrated by for example froth flotation before refining Note You will find a brief description of froth flotation on the introduction to metal extraction page The process
