Abstract Red Mud Recovery The aluminum industry is booming but with its mass production comes A Zero Waste Solution large amounts of waste known as red Team Members: Cory Brolliar (Robotics Engineering),Emily Molstad (Environmental Engineering), mud. This hazardous waste is not Connor Murphy (Aerospace Engineering), William Schwartz (ECE and CS), Kyle Tyler (Environmental Engineering), only an economical loss, but has Advisors: Prof. Brajendra Mishra serious environmental impacts such as leeching into the water Fluidized Bed Magnetic table. Many attempts have been Aluminum Plant made to utilize it from forming bricks Red Mud Plant Reactor Separation or mixing it in with cement but these solutions fall short. The struggle to dispose of this waste product may be Magnetite at an end as we turn to the potential Red mud + Coke 1300°C of red mud as a source for commercial materials. Red Mud Red mud is composed of fair amounts of iron oxide, additional alumina, titanium dioxide, calcium silicate, and trace amounts of rare Breakdown of Revenue *All values in billions of Air earth elements. The objective of this dollars Iron Oxide, 28.44 Aluminum project is to establish a system that Titanium Dioxide, 91 Sodium Aluminate efficiently extracts these materials Oxide 950°C Alumina , Slag + Sodium Carbonate individually and sells them to their 407.07 Dissociates in respective industries. After careful Water analysis of the processes required for Scandium, 907.1636 extraction and the profit made from Calcium Silicate, Cool Solution 950°C these metals, it has become evident 1.352 that red mud should no longer be considered a mere waste product. Total Revenue: $1.4 Trillion Calcium Silicate Titanium Slag Leached with Autoclaving Sodium Hydroxide Conclusion/Recommendation Composition of Red Mud by Percent -Iron Extraction by Fluidized bed reaction with metallurgical 300°C 90°C Weight coke Other -Aluminum Extraction by solid Na2CO3 reacting with the Iron Oxide Slag + Sodium Hydroxide 18% Calcium 30% Al2O3 at 950°C, yielding a water soluble NaAlO2. Once Silicate cooled with water to 25°C, up to 95% of the Al2O3 can be 17% extracted in pure form and sold for profit. -Titanium Extraction by sulfuric acid leaching Alumina -Rare Earths Extraction by autoclaving at 300 °C in presence 27% Scandium of 300-500 g of NaOH. 0.2% Selected Bibliography Titanium "Bauxite Residue Management."
