Summary

A new continuous process for conversion of copper mattes to blister copper has been successfully pilot-tested and is now ready for commercial application. The process, known as Kennecott-Outokumpu Flash Converting, involves reaction of solidified matte particles with industrial grade oxygen, in a flash furnace, to produce blister copper and a small quantity of slag which can be recycled to the primary smelting furnace. Production of low-volume high SO2 content offgases, separation of smelting and converting operations to allow increased on-line availability, and simplified process control are the major benefits of the process which translate to reduced smelter capital and operating costs.
