以β-萘酚钴渣为原料制取氧化钴的工艺研究

Study on Process of Preparing Cobalt Oxide by Using β-Naphthol Cobalt Slag as Raw Feed

进行了从β-萘酚除钴渣中回收钴-制取氧化钴的工艺研究,确定了工艺条件及参数。结果表明,该工艺能有效地除去锌、铁、锰、钙、镁等杂质制得纯氧化钴粉,钴的总回收率为90.37%。

By study on process of preparing cobalt oxide from β-naphthol cobalt slag, technical conditions and parameters were determined. According to the results, the impurities like zinc, iron, manganese, calcium and magnesium etc. were effectively removed to gain pure cobalt oxide powder by using this process with 90.37% total recovery of cobalt
