Bauxite, the raw material for the production of alumina, was first discovered in 1924 at Kijang, Bintan Island, in the province of Riau, in northwestern Indonesia. Bauxite from Bintan Island has been mined and exported since 1935. In 1968 ANTAM acquired the mine. Thus, ANTAM is Indonesia's longest running producer of bauxite.
Adopting the process of washing bauxite in the beneficiation plant can reduce caustic soda consumption and equipment and piping scale in the alumina refinery (OPEX), and consequently the payback for the beneficiation plant can be less than 3 (three) years. Besides the caustic consumption reduction, the beneficiation plant decreases the refinery ...

Ore), then from a stockyard ETO ore is transported to the washing plant area. But due to the buildup of material in stockyrad ETO area, the company does the initiative by conducting a direct feeding (ore mined from front area will be transported directly to the washing plant area without doing stock in stockyard ETO area).
limited to crushing, washing or wet screening and drying. Diffe.ences in thickness and hardness of the overburden, moisture content, inland transporta-tion requirements as well as infrastructure are reflected in the wide varia-tions in bauxite mining costs estimated in 1980 between US$12/mt and US$30/mt.
Estimation of ore washing potential and the selection of cut size is essential for the establishment of a bauxite washing plant. In the current research study, a simple ultrasonic washing technique has been developed for the removal of clay and to determine the potential of an industrial washing process at various cut sizes. Four feed size ...
The kaolinite dry mining process is a simple and economical process. The ore is crushed to 25.4mm by a hammer crusher and fed into the cage mill to reduce the particle size to 6.35mm. The hot air in the cage mill reduces the moisture of the kaolin from about 20% to 10%. The crushed ore is further ground by a blown-type Raymond mill …
Tables 6 and 7 present the mass balance details for line 2 for the washing, screening, and re-crushing circuits and for the hydrocyclone circuit, respectively. The balances were consistent, thereby offering the basis for evaluating the performance indexes of the plant and for calibrating the mathematical models of each equipment.
The chapter on bauxite residue (red mud) comprehensively reviews all aspects of bauxite residue from separation, management and disposal through to the …
liquor burning plant. Here, the liquor is concentrated by evaporation, slurried with fine alumina dust, and combusted in a rotary kiln. The organics are oxidised, and the resulting sodium aluminate is returned to the liquor circuit. 4.1.5 Precipitation Green liquor is passed to precipitation after being cooled via a heat exchange process. The
There are four water treatment plants located in the area of bauxite mining which are Bukit Goh, Bukit Sagu, Bukit Ubi, and Semambu Water Treatment Plant in Kuantan. ... Figures 6 and and7 7 shows a bauxite washing pond whereby the effluent water were discharged into Sungai Taweh which flows downstream causing severe …
More than 80% of Paragominas' bauxite is processed in hydrocyclones, equipment that presents a relative low classification efficiency regarding the presence of fine particles on the coarser flow being carried by respective water partition [].As a solution to mitigate this factor, the current plant design is composed of classification circuits in two …
