Turn red mud into steel

Scientists from the Vietnam Institute of Science and Technology have succeeded in "turning" large amounts of red mud discharged in the process of enriching and exploiting alumina (aluminum) from Boxit ore to create steel and cement additives. , pavement reinforcement .

The above success was implemented from the topic 'Research on turning red mud is a waste in the production of alumina (aluminum) into a useful product' by the Vietnam Institute of Science and Technology Institute of Chemistry. The main task of the project is to convert red mud to turn this waste into steel.

Accordingly, the research and development of products made from red mud meet both objectives. It is to reduce the amount of waste in the process of bauxite mining and processing, while taking advantage of the surplus waste in the exploitation and processing of ores to create materials capable of handling heavy metal ion pollution, and Other toxic substances in water. This is the current and pressing demand in the Central Highlands economic zones and many localities, such as Ha Giang, Cao Bang, Lang Son and Central Coast.

However, for technology to succeed, it is necessary to continue to research and perfect the technology, especially to reduce the price.
