Resumen

As an alternative method of reducing the large amount of slag generated during metallurgical processes in the primary copper production, it is to use the remaining iron in the slag as feed material for the iron and steel industry. The slag is generated during copper concentrates smelting in ratios ranging from 2 to 5 ton per ton of produced copper, and it contains 42–45% of iron. However, copper, sulfur and other detrimental elements affecting iron properties need to be reduced prior to use the slag in steel production. Therefore, some laboratory experimental run has been conducted to reduce copper by slag oxidation followed by leaching and recovering the dissolved copper by SX-EW, and smelting the solid with coke to produce a metallic phase containing 98% iron and 0.9% molybdenum. In further reducing steps, copper content is lower down and a molybdenum rich iron phase is obtained. Recovery of iron from copper slags considering reduction and control of harmful elements for iron properties was studied.
