摘要
用氮等离子体对高钛渣进行碳（氮）化处理，在１７００℃下停留１ｈ，可使渣中钛的碳（氮）化转化率达９２％，大于２０μｍ的Ｔｉ（Ｃ，Ｎ）晶粒约４０％。用重选方法选别碳化渣可得到含Ｔｉ（Ｃ，Ｎ）５０％以上的精矿，钛的回收率可达９０％以上。
Titanium-bearing blast furnace slag is carbonised in the nitrogen plasma. With the sample of slag held for 1h in the plasma furnace at 1700 ℃, 92% TiO2 in the slag can be transformed into TiC(N) and the diameter of 40% TiC(N) crystalline is more than 20 μm. Carbonized slag is separated by weight-dressing. As a result, the concentrate is obtained which contains TiC(N) of more than 50%, and the recovery rate of titanium can be more than 90 %.
