This paper reports a study that implements reverse flotation method to separate silica from West Kalimantan bauxite ores. The study is aimed to find the good process condition to obtain lowsilica bauxite as the feed for the Bayer process. The experiments were carried out in a 1 L of flotation cell tank. Dodecylamine was used as the collector, starch as the depressant, and MIBC as the frother.
· Higher amounts of iron and silica in metallurgical grade bauxite ore are considered to be disadvantageous to the Bayer's process in alumina production. Physicochemical processes such as froth flotation, reductive leaching, gravity separation and magnetic separation commonly used in bauxite beneficiation are expensive, energyintensive and ...

1. Introduction. Chinese bauxite ores have required more elaborated beneficiation processes than the Brazilian bauxite ores. This fact is a consequence of the low alumina/silica (Al/Si) mass ratio in currently mined Chinese ores (Xu et al., 2004).Despite Brazil having some reserves with highgrade alumina, the tendency towards the shortage of rich reserves has been discussed (Rodrigues, 2009 ...

· However, the high content of silica can not meet the production requirments of alumina. Desiliconization experiments were carried out during the process of one roughingone cleaning direct flotation in this work using diasporic highsilica bauxite as experimental ore samples, sodium oleate as collector and humic acid as depressant.
ctive only for the ore containing 4 to 5 reactive silica, in the light of the criteria enumerated above. Beneficiation of bauxite containing less than 45% silica was not found to be justifiable especially in view of the depletion of ore reserves. A typical economic analysis for bauxite containing 4'43°, reactive silica is summarised in Table Ill.
Quartz Ore Beneficiation by Reverse Flotation for Silicon . Oct 31, 2020 In this work the reverse flotation as beneficiation process for highpurity silica valorization from Draissa quartz deposits (Algeria) is studied as a potential raw material for photovoltaic silicon production and starting charge for crystal growth material for a large wide of appliions such laser and scintillation.

Abstract World reserves of bauxite include vast quantities of ore which at present are subeconomic due to high levels of reactive silica that cause expensive loss of caustic soda during Bayer processing. As the economic reserves of high grade ores diminish, attention is turning to how these lower grade ores may be processed at reasonable cost.
· the authors reported that reverse flotation can be applied to separate silica from bauxite ores from Tayan. The ratio Al to Si can be increased from 7 up to 14, by using dodecylamine as the collector [7]. While reverse flotation has been successfully applied to separate major silica from bauxite ores.
