The invention discloses a method for calcining ceramisites by using red-soil-type gold concentration tailings and a product thereof. The calcining method comprises the following steps: (1) uniformly mixing the red-soil-type gold concentration tailings, iron tailings and coal dust according to the mass ratio of 1.000:0.250-0.500:0.045-0.085, to obtain a solid mixture; (2) adding water which is 15%-30% of the mass percent of the solid mixture to the solid mixture, uniformly mixing and stirring, to obtain a solid-liquid mixture; (3) preparing a ceramsite base by using the solid-liquid mixture, and drying the ceramiste base to obtain the dried ceramiste base; and (4) calcining the dried ceramiste base for 5-20 minutes in 1050-1350 DEG C of the temperature, and cooling to obtain the ceramisites. The method is capable of improving the specific types of the key raw materials used by the calcining method. Compared with the prior art, the waste resource utilization of the red-soil-type gold concentration tailings can be realized in the ceramisites preparation.
