Hydrometallurgical Copper Extraction Process

2021-2-25  The successful development of the Cyprus Copper Process has been an evolutionary series of events covering a time span of some seven years. What does the Cyprus Copper Process do? Very simply, it converts copper concentrates of varying composition into copper metal which has been proven to be equivalent in every way to electrolytic tough pitch copper

Hydrometallurgical Process - an overview

In early stages, only two hydrometallurgical plants reached the commercial or semi-commercial level of direct processing of copper sulphide concentrates of copper in the 70s of the 20th century, both in the USA. One of them was Anaconda’s Arbiter Plant [15–18] which started production in 1974 with a capacity of 36 000 t of cathodes per ...
