摘　　要：研究了用生物质燃料粒还原焙烧水钴矿,再用硫酸浸出钴,考察了水钴矿粒度、生物质燃料粒加入量、还原焙烧温度和时间对还原焙烧产物中钴浸出的影响。结果表明,对于100 g粒度为-200~+325目的水钴矿,配入60目燃料粒10 g,混匀后在350℃下还原焙烧1.0 h,然后用硫酸从焙砂中浸出钴,钴浸出率达99.5%以上,浸出效果较好。Stainierite was roasted with biomass fuel pellets then used to leach cobalt.The effects of stainierite size,biomass fuel pellets amount,reduction roasting temperature and time on leaching of cobalt were examined.The results show that for 100 g stainierite,under the conditions of ore particle size of-200~+325 mesh,fuel of 10 g(60 mesh size),roasting temperature of 350℃,roasting time of 1.0 h,and then the calcine is leached using sulfuric acid,the leaching of cobalt is over 99.5%,and leaching effect is excellent.
