Dry beneficiation of Al2O3 25% to 55% is possible through various methods, including physical and thermal treatments. One possible approach is to use a method called "calcination," which involves heating the ore to high temperatures to drive off volatile components and promote the formation of higher-grade aluminum oxide.
During the calcination process, the ore is heated in a furnace to temperatures ranging from 1200 to 1400°C. This causes the impurities, such as silica and iron, to melt and separate from the aluminum oxide, which remains in a solid state. The resulting product is a high-purity aluminum oxide with a grade of up to 55%.

The production quantity of the upgraded aluminum oxide will depend on the initial quantity and the efficiency of the calcination process. However, it's important to note that not all of the aluminum oxide in the initial ore may be recoverable, as some may be lost during the calcination process or converted to other compounds.
Dry beneficiation has the advantage of saving water, a valuable resource, and not requiring a tailings pond, which can help prevent the leaching of trace/toxic elements into groundwater.

Overall, the output quantity of the upgraded aluminum oxide will depend on various factors, including the initial ore quality, the calcination process efficiency, and the optimization of the calcination parameters. It's recommended to conduct a detailed feasibility study to estimate the expected output quantity and the cost of beneficiation.
Cost of calcination bauxite beneficiation plant in India of 200 tph and the raw material required for the process.
The cost of a calcination bauxite beneficiation plant in India with a capacity of 200 tph can vary depending on several factors, including the specific design and configuration of the plant, the type and quality of the raw materials, and the location and availability of utilities and infrastructure. However, based on industry estimates, the cost of a 200 tph calcination bauxite beneficiation plant can range from $10 to $30 million, depending on the complexity of the plant and the specific requirements of the project.
As for the raw materials required for the calcination process, bauxite ore with a high alumina content (typically above 40%) is the primary raw material. Other materials that may be required include fuel for the calcination process, such as natural gas, coal, or oil, as well as refractory materials for the construction of the kiln and other equipment. The specific type and quantity of fuel and refractory materials required will depend on the design and configuration of the plant, as well as the properties of the bauxite ore being processed.
It's worth noting that the calcination process can be optimized to increase the recovery rate and reduce the loss of aluminum oxide. This can be achieved by controlling the calcination temperature, the residence time, and the flow rate of the ore through the furnace. Additionally, the use of advanced process control and automation technologies can help improve the efficiency and reliability of the calcination process, while minimizing energy consumption and emissions.
