Aluminum Rocks, Aluminum Oxide, Chlorine gas, Tala and Barfak MineAbstract
The basic raw material for the production of Aluminum and its citrus fruits is bauxite, which contains more than 50% of Aluminum oxide, but the lack of its natural resources in sufficient quantities in many countries has caused more attention to be paid to other Aluminum-bearing rocks. This study investigated the extraction of Aluminum and Iron oxides from Aluminum rocks of the Tala and Barfḵ mine in Chlorine Gas atmosphere. The effects of temperature, particle size of the ground Aluminum rocks, residence time of the materials in the reaction zone, and the amount of Chlorine gas consumption at different times were also investigated. The samples were first ground to a size of 0.01-0.03 mm using a laboratory mill and then placed in a reactor. The reactor was activated and a continuous flow of Chlorine gas was passed through it at different temperatures. The chlorination process was carried out at different temperatures. The results of the analysis, using an atomic absorption device, showed that about 56.128% of Aluminum oxides and 68.4% of Iron oxides were obtained in the first 60 minutes. Increasing the time to 120 minutes had a little effect on the conversion degree. Also, in this experiment, the optimum temperature was determined to be 650 °C and the particle size of the ground Aluminum rocks was 0.01-0.03 mm. The duration of stopping the materials in the interactive area was 60 minutes and the consumption of Chlorine gas was fixed at about 15 milliliters per minute
