“…For example, the conditions for El Teniente Converter Process, where the white metal with about 75 wt% Cu and slag nearly saturated with silica and magnetite with high content of copper (7-10 wt% Cu, 12-16 wt% Fe 3 O 4 ) coexist with high partial pressure of oxygen in gas phase are indicated in Fig. 2 by ones shadow area [14]. Another shadow area represent the condition in El Teniente Slag Cleaning Process, where coexist matte with about 60 wt% of copper and slag saturated with silica and iron having low copper and magnetite content (0.79 wt%, 11.25 wt% Fe 3 O 4 , 0.56 wt% Fe met. )…”

The Chilean copper smelters are producing large amount of copper slags. These copper slags are deposited at landfills. In the present time, a huge amount of copper slags are accumulated in Chile. The main problem with landfilling is not only the land space, area which is used for copper slags deposition every year, but many environmental problems, high disposal and transport cost are associated with the landfilling of these slags. Therefore, the focus of environmental policy is now into waste minimization and recycling to minimize transport and disposal cost, saving resources as well as land space. Copper slag contains many useful metals and slag making oxides, which can be recovered and recycled by a high temperature direct reduction process. The laboratory scale tests show that by suggested high temperature direct reduction of copper slags two products can be obtained, a Fe–Cu–C alloy with precious metals content and an inert slag with low metal content. The Fe–Cu–C alloy can be used for metal production and inert slag for cement production similar to blast furnace slags. Suggested high temperature direct reduction process for copper slags treatment is commercially feasible and environmentally friendly without any solid or liquid waste.
