Get PriceCopper concentrators typically treat up to 100 000 t of ore per day. They are located directly at the mines to achieve low transport costs. The copper recovery efficiency is over 90 %. About 95 % of the ore input goes into the tailings, which are stored in large dams near the mine and are used for water recycling to the flotation stages. Separation of special copper ores such as those ...
Get PriceCopper smelting involves three steps: Roasting: First, ore concentrates are roasted or heated to remove sulfur and moisture. Smelting: Then, copper concentrates are mixed with silica (sand) and limestone and heated in a furnace to form two naturally-separating layers. One layer is a waste containing iron and silica compounds and is discarded as slag slagByproduct left after a desired metal is ...
