Abstract
Disclosed herein is a method of treating spent pot liner (SPL) material or materials having similar compositions thereto, the method including the steps of: Placing a SPL mixture into a kiln (preferably a counter current fired rotary kiln), wherein the mixture includes SPL material, a silicon source (preferably selected from one or more of silicon dioxide, waste glass, silicon sand), a calcium source (preferably selected from one or more of calcium carbonate, calcium oxide, calcium hydroxide) and an iron source, and Heating the SPL mixture to a tempereature in the range of 1050°C to 1150°C to cause combustion of the carbon in the SPL material and melting of the SPL mixture to form a slag, and Discharging the resulted slag from the kiln, The method being characterised by: Ensuring the percentage of iron within the net SPL mixture is in the range of 5-20%w/w.
