Refractories for Copper Production: Mineral
2018-6-17 Over the past generation, copper producers have adopted refractory materials biased on the MgO-Cr 2 O 3 system to meet these challenges, to the point where ‘mag-chrome’ brick is used almost exclusively in the industry. However, recent environmental imperatives have created a need to develop chrome-free alternative refractories for copper smelters, converters and refining furnaces.

Chromite - an overview ScienceDirect Topics
Concentrates made from UG2 ores contain considerable chromite, FeCr 2 O 4. The melting point of the slag is raised because of the chromite content. In addition, the chromium from the chromite may cause precipitation of the (Fe,Mg)Cr 2 O 4 spinel, which has a melting point of about 1600 °C, in cooler parts of the furnace (Nelson et al., 2005).
