description The invention relates to the field of chemical methods for extracting vanadium, and in particular relates to a method capable of greatly improving the conversion rate and leaching rate of vanadium forroasting a vanadium-containing material by using a chain grate machine and a rotary kiln. The method comprises the following steps: a, crushing the vanadium-containing material to a required particlesize, mixing the crushed particles and additives, and performing mechanical activation to obtain a mixture; b, uniformly arranging the formed material in the chain grate machine by using a roll screening machine, and performing drying, curing and strengthening in the chain grate machine; and c, allowing the formed material to enter the rotary kiln for concentrated high-temperature roasting, performing discharge to obtain a vanadium-containing formed clinker, crushing the vanadium-containing formed clinker to a required particle size, and performing water leaching or acid leaching to obtain avanadium-containing leachin
