The output of the copper smelting slag is huge, and the output is increased year by year, particularly the slag growth is more obvious in the years. The huge copper slag reserves not only cause environmental pollution, but also waste a large amount of resources. As a main byproduct in the copper smelting process, the copper slag contains a large amount of valuable elements which can be recycled, wherein the iron content in the copper slag reaches more than 30 percent and exists in the forms of FeO and Fe3O 4. With the increasing awareness of people in building resource-saving and environment-friendly society, many scientific research institutes and engineering technicians in universities and universities begin to conduct a great deal of laboratory research and industrial tests on the recycling of iron from copper slag.

Through experimental research, the method finds that the oxygen-enriched side-blown converter is adopted to smelt the most suitable copper ore slag iron for recycling, the requirements of the oxygen-enriched side-blown smelting on the state and the grade of the ore are low, the investment is light, the occupied area is small, and the operation is simple.
