    Beneficiation Of Fine Weipa Bauxite Tailing

    Two types of Bauxite are mined in Weipa, Northern Queensland, and are designated as Andoom and Weipa ores depending on the deposit. To improve the grade of these ores washing is usually done which results in a lot of the constituent siliceous material being washed away. The resultant bauxite product then achieves a grade of about 60 Alumina with about 5 Silica.
