The typical range of cost is $3,000–$5,000 (US$) investment per annual tonne of copper production ( e.g., $900 million to $1.5 billion for 300,000 tpa Cu production). The unit cost will vary according to scale and location. The high capital cost of smelters/refineries is partly offset by low operating costs.

اقرأ أكثرThe total-oxidation process is particularly advantageous for copper–gold ores. Gold can be recovered by direct cyanidation of the washed autoclave solids. Silver, if present, will likely be fixed at least partly as silver jarosite in the autoclave solids. To improve silver recovery, a lime boil is recommended (2 h at 95°C with an excess of CaO).
