    Hydrometallurgical Processing - 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 annum. The process was based on the ammonia oxidation leaching of the
