中文摘要: 在空白焙烧酸浸工艺的基础上,考查了微波加热浸出和常规加热浸出对某含钒石煤中钒浸出率的影响。结果表明,在浸出温度98 ℃、焙烧样粒度-0.074 mm占75%、硫酸体积分数20%、浸出时间90 min、液固比1.5︰1(mL/g)时,微波加热的钒浸出率为88.2%,比相同条件下常规加热浸出高9个百分点。
Abstract:The effects of microwave heating and conventional heating on vanadium leaching rate from vanadium-bearing stone coal were investigated based on blank roasting-acid leaching of vanadium. The results show that microwave irradiation leaching rate of V2O5 is 88.2%, approximately 9 percentage points higher than that of conventional heating, under the conditions including leaching temperature of 98 ℃, particle size of -0.074 mm of 75%, volume fraction of sulfuric acid of 20%, leaching time of 90 min, and ratio of liquid to solid of 1.5︰1 (mL/g).
