Abstract:
     This process belongs to the production technique of aluminium hydroxide or aluminium oxide. Its main technic characteristic is that SiO2 contained in the ore is also added with a corresponding amount of lime, pressure-boiled and soaked out from the ore, so that SiO2 may be partially or wholly generated watery calcium aluminosilicate, thus the chemical loss of alkali is decreased or avoided. Additionally, red-mud can be used to produce silicate or other kind of cement, and to ultilize the waste and reduce environmental pollution is rechieved too.
