<p>PURPOSE: A method for manufacturing glass tiles using coal ore is provided to simplify manufacturing processes and to recycle resources by mixing coal ore, soda ash, silica, cullet, calcium-based materials, and magnesium-based materials. CONSTITUTION: A method for manufacturing glass tiles using coal ore includes the following: Coal ore, soda ash, silica, cullet, calcium-based materials, and magnesium-based materials are mixed to obtain a mixture(S1). The mixture is molten and is shaped into a glass sheet(S2, S3). The glass sheet is plasticized. The coal ore is coal-preparation refuse. The melting process of the mixture is implemented at a temperature between 1300 and 1700 degrees Celsius for 0.5 to 5 hours. An annealing process is followed.</p> |
