The invention discloses a purification method for ceramic production, which comprises a fixed bottom plate, the top of the fixed bottom plate is fixedly connected with a main body, the left side of the top of the main body is fixedly connected with a control panel, and the right side of the position, far away from the fixed bottom plate, of the main body is provided with a sintering device; and connecting frames are fixedly connected to the middles of the outer walls of the two sides of the sintering device, and a purifying device is fixedly connected to the left side of the position, away from the fixed bottom plate, of the main body. According to the purification method for ceramic production, follow-up processing work is facilitated, the processing time can be shortened, the working process in the device is in a sealed state, and the internal movement range is limited, so that the situation of dust raising during work is avoided, produced powder is fully collected, and the production efficiency is improved. And meanwhile, after high-temperature calcination, the structure of the raw material is destroyed, so that the raw material loses magnetism, full utilization of the raw material is facilitated, and the processing quality of the powder is improved.
