The raw materials in copper smelting contain generally 6–14% moisture. The level of moisture classifies smelting as either a wet-feed or a dry-feed process. Requirements of the moisture content of feed vary from process to process. The most demanding processes are flash smelting and the Mitsubishi process, which require dry concentrates (<0.5% moisture).1 Reverberatory furnaces can tolerate a maximum of 7% moisture in the feed; and ISA furnaces and Noranda reactors, up to 10% moisture. Compared with dry feed, the use of wet feed in copper smelting has disadvantages, such as increased energy consumption and off-gas flow. Hengyang Company describes the benefits of drying the copper concentrate, presents different drying technologies, and demonstrates the superiority of the rotary steam dryer.
