Carbon Refractory cement in an Oxidizing Process? Copper Smelting in an Outotec

Carbonaceous refractory materials refractrory cement are widely accepted in many reducing smelting processes such as iron and ferroalloys. Oxidizing processes such as copper concentrate smelting traditionally use magnesia or alumina/silica refractory materials refractrory cement . The main objection to carbon-based refractories in oxidizing applications is the potential for free oxygen to react with the carbon at high temperature, which could rapidly degrade the refractrory cement lining. In 2013, Outotec and GrafTech conducted joint trials of a thermally conductive, carbonaceous lining for smelting copper concentrates in the Outotec® pilot-scale top-submerged-lance (TSL) furnace in Dandenong, Australia. This testwork had two equally important goals; demonstrate the ability of carbon refractories to withstand oxidizing process conditions, while ensuring that neither furnace operating conditions nor process stability were negatively affected by the refractory material refractrory cement . The paper discusses the input parameters of the trials, key observations during the testwork program, and the results and conclusions from both process and refractory refractrory cement  design standpoints.
