<p>PURPOSE: A far infrared emitting grinded ore mixture is provided, which distinctively decreases exhaust gas and dioxin formed by incineration and protects environment by using waste ore. CONSTITUTION: The grinded ore mixture is obtained by mixing 55-60% of mining byproduct and 40-45% of inorganic ore. The mining byproduct is prepared by sintering waste ore at 400-600°C to eliminate impurities, then grinding to a sand size. The inorganic ore is prepared by sintering far infrared emitting inorganic ores such as sericite mica, zeolite and mineral stone(mekbanseok) at 600-700°C, then grinding to a sand size.</p> |
