Main aim of Romelt process is not mass hot metal production, which is successfully realized by blast furnace route, but recycling of toxic iron-bearing wastes and provision of mini-mills with hot metal as a substitute of scrap, which at present is in a short supply. Maximum output of Romelt furnace makes about 350 thousand tons of hot metal per year, which can be increased by running several Romelt furnaces at a time; exclusion of coke ovens and sinter plant from this technological scheme gives undisputable economic advantages. Romelt furnace design allows to use it for gasification of solid fuels and recycling of solid domestic wastes. World ferrous metals production amounting to more than 2 billion tons per year is accompanied by generation of 5 10% wastes. Though at present some current wastes undergo processing, which is still incomplete, but dump yards containing up to 50% iron are not utilized at all due to non-availability of acceptable technology. High content of non-ferrous, alkali metals and sulfur in these nonutilizable wastes causes irreversible damage to environment due to their washing out by atmospheric precipitates to soil and waters. Non-ferrous metallurgy enterprises and some other production facilities face similar problems. Utilization of Romelt plants at the end of production chain of these enterprises guarantees wasteless recycling of current and dump yard wastes. One such furnace is sufficient for processing the entire amount of current wastes. At present we observe steady tendency of growing steel output at mini-mills with EAF route in which steel scrap is used. Scarcity of scrap in the world and its contamination with non-ferrous metals represent serious problems for promoting this steel production route. Construction of Romelt furnaces at mini-mills allows to solve this problem. Design and technological features of Romelt process allow to use it for recycling of solid domestic wastes, especially unsegregated ones, including liquidation of dump yards. This technology has been realized with financial assistance of Samsung Heavy Industries (South Korea) at the small scale pilot plant intended for processing of various solid wastes such as broken glass, coal ash etc. Capital investments related to construction of Romelt furnace intended for recycling of solid domestic wastes make about US$ 300 for processing one ton of waste.
