中文摘要: 首次采用褐煤取代二氧化硫在硫酸介质中浸出钴土矿,考察工艺条件对钴土矿浸出的影响。结果表明,在下述最佳条件下,钴浸出率大于97%:煤粉粒度-0.074 mm占98%、煤矿比0.33、酸矿比0.45、液固比2、温度92 ℃、浸出时间5.5 h。
Abstract:Sulfur dioxide was substituted by lignite to leach asbolite in sulfuric acid system for the first time. The effects of technical conditions on leaching of asbolite were investigated. The results show that cobalt leaching rate is 97% above under the optimum conditions including particle size of lignite of -0.074 mm of 98%, ratio of lignite to asbolite of 0.33, ratio of liquid to solid of 2, temperature of 92 ℃, and leaching time of 5.5 h.
