· 2.1. Refractory Materials Preparation and Characterization. In the investigations six commercially available oxides and spinel refractory materials (numbered 1–6) were tested to study their corrosion by Na 2 CO 3.The three oxide refractory samples are (1) Al 2 O 3 (2) Fe 2 O 3 and (3) Cr 2 O 3 and the other three spinel refractory samples are (4) magnesium chromium (MgO·Cr 2 O 3) (5
An overview of the design operation and maintenance
This operation is conducted from a refractory-protected mudgun cabin. The operator then lowers the mudgun and rams the clay into the tap-hole. In the event of a mudgun failure manual clay stoppers are used to close the tap-hole. Clay consumption is measured after every matte tap.

The potential for catastrophic cooler failure and/or furnace refractory breakout (Zhou and Sun 2013 Newman and Weaver 2002) within most commonly a few minutes of mudgun closure is high (Hundermark et al. 2014). A breakout following mudgun closure has even prompted one PGM producer to resort to drilling and lancing but to closing tap
