Copper Mining and Processing: Processing Copper Ores

1   Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 9999% pure copper called cathodes, which will ultimately be made into products for everyday useThe most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and Annual copper production from Constancia is expected to average 110,000i tonnes over the next three years, a 23% increase from 2022 levels Annual gold production from Snow Lake is expected to average more than 190,000i ounces over the next three years, a 30% increase from 2022 levels Peru concentrate inventory levels at site have reached normal Hudbay Provides Annual Reserve and Resource Update
