Sep 01, 2002· By 1977, the SX-EW process had improved such that most production now resulted in a high-quality cathode that could be directly used by wire rod plants, without further refining (Jolly, 1991). This made the SX-EW process superior to cement copper in terms of product and cost; production of SX-EW copper rapidly increased.

mill capacities. These costs were estimated from inhouse historical data for a variety of plant capacities, as illustrated below. These estimates were based on a hypothetical mine with the key assumptions, as outlined below in Table 3.
