Zapping 'red mud' in plasma turns mine waste into valuable iron …
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.

IRON ORE VALUE CHAIN
Iron is produced by smelting iron ore with a high-carbon fuel and reductant such as coke (coking coal), usually with limestone as a ux (to reduce the temperature at which the iron melts). Most crude steel is produced in a basic oxygen furnace where molten iron (from the blast furnace) is combined with steel scrap (<30%) and small amounts of ux.

Iron ore mining and dressing
An ironworks (or iron works) is an industrial plant for the production of steel from iron ores! Before the iron ores can be fed to the ironworks, they must first be mined (ore extraction) and specially processed for the blast furnace process (ore processing). These process steps are described in more detail in the following sections.
