| 摘 要： | 对硫酸钠熔炼法处理废硬质合金得到的钴渣,用Ｘ射线仪（ＸＲＤ）进行相分析,证实了现行硫化钠熔炼工艺中,钴以Ｃｏ９Ｓ８形态存在;根据相图分析了Ｃｏ９Ｓ８的成因;提出了用氧化焙法处理Ｃｏ９Ｓ８的工艺。试验结果表明,用氧化焙烧法处理钴渣,钴的浸出率可达９９％以上。

| Abstract: | The Co slag obtained from scrap hard metal smelting with Na 2SO 4 was analysed by XRD. Results show that the Co in the slag is in the form of Co 9S 8. Analysis of Co 9S 8 by phase diagram shows its formation mechanism, and oxiding roasting method for the Co slag treatment was put forward. Results show that after oxiding roasting of the Co slag,the leaching rate of Co is more than 99%. |
