What is Red Mud?
- Red Mud is composed by a mixture of solid and metallic impurities
- The red color is caused by the oxidized iron present in the mud, it can make up to 60% of the mass of the red mud.
- Red mud cannot be easily disposed. In most countries where red mud is produced, it is pumped into red mud ponds. These "ponds" are simply areas full of red mud.
- Red mud presents a problem because of its toxicity and also it takes up large areas of land unnecessarily. This is because red mud cannot be built on, even when dry.
