研究了焙烧、硫酸与石煤质量比、浸出温度、液固比、石煤磨矿细度和两段逆流浸出对钒浸出率的影响。结果表明，在硫酸与石煤质量比为20%，浸出温度为95 ℃，浸出时间为30 h，液固比为1.1 mL.g（-1），磨矿细度为0.1 mm的条件下，焙烧石煤的两段逆流浸出钒的浸出率可达65.1%，可为石煤制钒提供实验依据。
The effects of roasting, mass ratio of H2SO4 to stone coal, leaching temperature, liquid-to-solid ratio, grinding fineness of stone coal, and two-stage counter-current leaching on the vanadium leaching ratio were studied. The results show that the vanadium leaching ratio of roasted stone coal through two-stage counter-current leaching can reach 65.1% at the mass ratio of H2SO4 to stone coal of 20%, leaching temperature of 95 degrees C, leaching time of 30 h, liquid-to-solid ratio of 1.1 mL.g(-1), and grinding fineness of 0.1 mm, which can serve as an experimental basis for the production of vanadium from stone coal.
