Mintek’s Pyrometallurgy Division carries out high-temperature research and process development for the production of a wide variety of mineral commodities. The division is perhaps best known internationally for its large-scale piloting of electric smelting processes, especially in DC arc furnaces. There is also substantial expertise in thermodynamics, process and arc modelling, high-speed photography, metal condensation, and furnace design. The largest furnace that Mintek has is a 3 MW DC arc furnace that has a 4.25 m diameter shell. Other pyrometallurgical equipment available includes a well-equipped high-temperature laboratory, externally heated rotary kilns, a flash drier, and a top-blown rotary converter (TBRC).
Related services include optimisation, trouble-shooting, and toll smelting.
