ABSTRACT Bauxite is an important mineral ore that is widely used in aluminum industry for metallurgical and refractory purposes. However bauxite contains silica as an impurity which degrades its quality. Silica forms complex with the caustic used during the processing of ore thereby forming precipitates. This leads to unnecessary wastage of caustic that contributes to …

Each type of bauxite ore presents its own challenges in terms of mineral processing and beneficiation for the generation of alumina [7,8]. Normally, the beneficiation or treatment of bauxite is limited to crushing, sieving, washing, and drying of the crude ore [3]. Flotation has been employed for the upgrading of certain low-grade bauxite ores,
The silica present in the bauxite tends to be concen-trated in the finer grained fractions, and this charac-teristic makes bauxite amenable to beneficiation by screening techniques. Pearson' has reported that in a bauxite of average composition of 1.58% silica, the minus 100 mesh fraction analysed a silica content as high as 10.30%.
Aluminum oxide, or alumina, is the primary component of bauxite. Processors remove the impurities from the bauxite ore through bauxite beneficiation and separate the aluminum. Ore washing is a standard means of performing bauxite beneficiation, as it represents the most effective means of obtaining the highest level of aluminum-silicon ...
Bauxite is of a fragmented nodular type ore which requires beneficiation. The biggest occurence is at Paragominas (Para State) with its 2,5 Bt of crude ore from which about 1,5 Bt can be …
1.1. Beneficiation Process of Bauxite Generally, four to six tonnes of bauxite ore are required to produce one bauxite processing increasestonne of aluminium metal. Iron and titanium compounds, found as impurities in bauxite ore, remain insoluble in caustic solutions and transform into red mud after digestion.
The first publications on Suriname's bauxite date back to 1903, and several studies on the bauxite deposits and their origin followed.
