The invention relates to a method for extracting vanadium from vanadium-containing stone coal through a manganese-doping heap procedure. The following technical scheme is adopted: the method comprises the following steps: stirring a vanadium-containing stone coal powder, an MnO2 powder and a cotton straw powder at first, and then adding concentrated sulphuric acid and an effluent of a macroporous anion exchange resin bucket and adequately mixing; then conveying a stirring mixture into a large special heap pool, and airtightly accumulating for 36-72h to carry out a carbonization-oxidization reaction; shovelling out a heaped product in the subsequent procedure, and preparing V2O5 with a concentration of more than 99.5% through the processes of adding water and stirring to leach vanadium, carrying out solid-liquid separation, adjusting the pH value of a leaching solution, adsorbing vanadium through macroporous anion exchange resin, eluting vanadium through strong base, carrying out vanadium precipitation and roasting, and the like. The method disclosed by the invention has the following maximum characteristic: large-scale heap pre-treatment is carried out on the vanadium-containing stone coal through doping biomass, an oxidant and the concentrated sulphuric acid in a mode of gold heap leaching. According to the method, decarburization roasting for ores is not required, waste gas is avoided, a high vanadium leaching rate is achieved, and the method is a new and environment-friendly vanadium extraction method.
