Continuous process for copper smelting and

Continuous Copper Smelting Processes . Three continuous copper smelting processes have been tried on a pilot plant scale and two of those are currently in operation. These processes are known as the WORCRA, the NORANDA, and the MITSUBISHI process. In a WORCRA process, it is suggested to perform smelting and converting in a single furnace, with the matte and slag flowing countercurrently.
