A self-propagating combustion cyclone reactor includes a reaction chamber delimited by a circumferential wall in which at least one reductant inlet and a plurality of oxidizer inlets are formed in a tangential manner. Reductant and oxidizer are fed, together with inert gas, through the inlets into the chamber in a cyclonic manner to induce self-propagating combustion reaction to generate a product of high purity metal, such as titanium, zirconium, hafnium, or silicon, semiconductor substance. The reactor serves as a continuous reactor for generation of metal or semiconductor substances of high purity.
