Bauxite Calcination Plant

Gadhshisha Calcination Project   In order to produce further value-added material from plant grade bauxite, GMDC has set-up Calcination plant at Gadhshisha where bauxite is calcined at plant temperature in a rotary kiln. The plant capacity is 50,000 tonnes of Calcined Bauxite per year. Recently, the Corporation has introduced Dual Firing System to operate the plant on 70:30 ratio of Petcoke and furnace oil as a fuel; whereby the cost of production is expected to reduce by about Rs.500/- per MT of calcined bauxite. As such, the profitability would increase substantially and we would be in a position to withstand stiff competition in the market in sale of our product. The chemical analysis of Calcined Bauxite produced in our plant is as under :   Al2O3 Min.86% SiO2 Max.3.5% Fe2O3 Max.3% TiO2  Max.2% CaO  Max.1.2% LOI  Max.0.5% Bulk Density +3   General:Calcined Bauxite Project was established in year 1992.  The raw material used for calcination is bauxite. Bauxite is Al2O3, 2HO2 in chemical composition.  GMDC is having  different mines located at various distance from Calcination Plant, Gadhsisha.  The details are as under :-    Sr.No. Name of Mine Taluka Area in ha Mine capacity 1.
