Chapter 2. Production and Processing of Aluminum

1999-5-7  The starting material for electrolytic smelting of aluminum is pure, anhydrous alumi-num oxide (Al 2 O 3) called alumina. In the Western World, the Bayer 1 process, invented in the 19th century, is by far the most important process used in the production of alumi-num oxide from bauxite. The process has been refined and improved since its inception.

2021-4-5  In this work, extraction of lead from Electrolytic Manganese Anode Mud (EMAM) by microwave coupled ultrasound was studied. The results showed that microwave roasting promoted the conversion of MnO 2 to Mn 2 O 3 and Mn 3 O 4, which greatly facilitated the subsequent leaching process of lead and the introduction of ultrasound effectively enhanced the leaching process.
