Outline of Final Research Achievements

As one of the new applications of copper smelting slag, we aimed to construct a process of slowly cooling for the slag, crystallizing magnetite, and separating by physical separation. Focusing on the magnetite expected as both iron resources and a carrier of many other useful metals, the influence on the production amount and grain size of magnetite by process conditions such as slow cooling rate and temperature retention was systematically examined using both the simulated and the actual slag. It was confirmed that grain size that is enough for physical separation can be obtained by slow cooling rate under 3 K / min. After slow cooling, by grinding and high gradient wet magnetic separation, it was confirmed that magnetic products with equivalent iron grade without copper contamination could be obtained.
