· The first step in making aluminum is to mine a rock called bauxite, which is rich in aluminum oxide, also known as alumina. Extracting the alumina leaves behind waste called red mud that is highly alkaline and can also contain toxic heavy metals such as cadmium. Every year this process generates about 180 million tons of red mud.
