Abstract
According to the invention, after having previously crushed and ground a starting material containing silicon carbide, the latter is treated by separation in a dense medium, such as one comprising ferrosilicon or a suspension of magnetite in water. There is obtained a concentrate of silicon carbide without having to use the step of manual sorting.
