Method for preparing ecological active residues by treating electrolytic manganese residues by using tunnel kiln device
The invention relates to a method for preparing ecological active residues by treating electrolytic manganese residues by using a tunnel kiln device. The method comprises the following steps: (1) blending and homogenizing: blending 45-75 parts of electrolytic manganese residues, 8-25 parts of stone coal, 14.7-45.0 parts of waste rock residues and 0.3-2.0 parts of an alteration agent, grinding the mixture into powder, adding 5-15 parts of water, and uniformly and homogenizing the mixture to a plastified material; (2) molding: molding the plastified material to a rod-like or bulk-like molded material; and (3) calcining the tunnel kiln: sending the molded material in the tunnel kiln, calcining the molded material for 20-60 minutes at 980-1300 DEG C, and quenching the molded material to obtain the ecological active residues. The ecological active residues contain various hydrated active minerals, can be widely used for cement industry, is high in strength if being used, and is easy to slurry and high in strength if being used as masonry cement or cement making bricks. The method provided by the invention is low in investment, free of wastewater and waste residues and good in economical benefit.
