This invention discloses a method for thermal activation of coal gangue. Using coal gangue and an activating admixture as raw materials, the method involves sequential crushing, mixing and mechanical activation, homogenization, molding, drying, calcination and thermal activation, cooling, and grinding to prepare active powder.
