我厂几年来的生产实践证明,含钴黄铁矿硫酸化沸腾焙烧钴的可溶率一般保持在75％左右。去年,我们对沸腾焙烧添加芒硝以提高钴的转化率的问题进行了探讨。通过生产试验取得了较好的效果:在相同条件 Production practice in our plant over the past few years proved that cobalt pyrite sulfated boiling roasting cobalt generally remains at about 75%. Last year, we discussed the problem of adding mirabilite to the roasting roasting to increase the conversion rate of cobalt. Through the production test achieved good results: the same conditions
