This invention discloses a method for purifying reducing agent coal used in industrial silicon production, belonging to the field of chemical raw material purification technology. The invention provides a purifying agent that enters the interior of the reducing agent coal through the pores to carry out an iron removal reaction. Nonylphenol polyoxyethylene ether promotes the dissolution of oxalic acid in water and inhibits foam formation. Iron in reducing agent coal used in industrial silicon production mainly exists in two modes: Fe2O3 accounts for 40%-50%, and FeS accounts for 50%-60%. Since Fe2O3 can react with oxalic acid (H2C2O4) to form a precipitate that is insoluble in water, washing with water after soaking achieves the purpose of iron removal. The method of purifying reducing agent coal used in industrial silicon production using a purifying agent can significantly remove trace impurities such as Fe, Al, and Ca that affect the quality of industrial silicon products.
