        國內將含鈷的黃鐵礦和磁黃鐵礦精礦通稱鈷硫精礦,是國內主要煉鈷原料之一。南京鋼廠、葫蘆島鋅廠、湖北光化磷肥廠和山東淄博鈷廠四個廠家利用這種原料。其中葫蘆島鋅廠的產品是二號電鈷,采用硫酸化焙燒→浸出→脂肪酸脫鐵銅→沉鈷→還原鑄陽極→陽極液凈化→隔膜電解的方法,因生產成本高,現已停產。南京鋼廠曾采用氧化焙燒——燒渣中溫氯化焙燒工藝,湖北光化磷肥廠采用氧化焙燒——燒渣硫酸化焙燒工藝。但由于鈷硫精礦含鈷太低,一般都小于0.3%,加上回收鈷的工藝流程復雜,普遍無利可圖,所以,這些廠在生產一段時間后,又停止了生產。山東淄博鈷廠利用鈷硫精礦和含鈷原料生產硫化鈷、氧化鈷、氯化鈷、硫酸鈷等產品。
