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

Degradation mechanisms and use of refractory linings

2014-3-1  Burned bricks with direct bonding between the chromite and periclase offer improved hot strength, lower porosity and permeability and higher spalling resistance. These burned direct-bonded bricks, and at higher temperatures burned bricks made of prereacted material (co-clinker or fused grain), are the main refractories for copper production. 5. Especially when corrosion resistance is highly

Carbon Refractories in an Oxidizing Process? Copper ...

Oxidizing processes such as copper concentrate smelting traditionally use magnesia and/or alumina/silica refractory materials. The main objection to the use of carbon-based refractories as the exposed working lining in oxidizing applications is the potential for free oxygen to react with the carbon at high temperature, which could rapidly degrade the refractory lining.

Interaction of Chrome-Free Refractories With Copper ...

2018-6-8  Concern over the potential labeling of spent mag-chrome brick from copper production furnaces as hazardous waste has led to a joint research program by the University of Missouri-Rolla (USA) and the G.K. Williams CRC for Extractive Metallurgy (Australia) to assess the usefulness of potential alternative materials, focusing on refractories in the magnesia-alumina system.

Degradation mechanisms of alumina-chromia

2018-5-15  Long-lasting refractory linings for furnaces in copper-making industries, where high cost magnesia-chromite bricks are the most extensively used material, are desirable based on economic and environmental considerations. An extended lifespan of the refractory lining can reduce production losses during downtime of the furnace [ 1 ].
