Beneficiation of fine Weipa bauxite tailing

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

The plant produces copper cathodes from concentrator tailings and reclaimed tailings. The process was initially based on the acid leach–cementation process. However, the advent of the solvent extraction technology led to the plant being upgraded in 1973/1974 which greatly increased the utility of hydrometallurgy in the extraction of copper ( Chisakuta et al., 2005 ).
