 · Abstract. Slag dumping and water granulation are the most commonly used slag treatment methods in the metallurgical industries. In both processes, water is present (by desire for cooling and dispersion or as a result of rain accumulation) and thus equipment and operations are designed to minimize and mitigate the risk of steam explosions resulting from the inappropriate contact of slag …

Site from 1872 to 1971. Smelting produced a waste product called slag, which was deposited on the Site and adjacent tidelands. Due to decreasing business demand and increasing environmental regulations, smelter decommissioning began in 1971. Construction of asulfuric acid plant and liquid sulfur dioxide plant took place in the late 1930s and 1940s.

Growth in Brandenburg: On 1 January 2020, the STEAG Power Minerals Group acquired the majority of the shares in a slag treatment plant in Zossen. In future, slag and ash from STEAG''s waste to energy plants will be processed there and returned to the economic cycle – with high potential for creating value.

Dry Slag Granulation. Water granulation is the most commonly used method to handle blast furnace slag and requires a granulation and a dewatering step to process the slag. In water granulation, the energy in the slag is lost from water evaporation and cooling and is difficult or impossible to recover.

 · A Fine Slag Treatment Plant (FSTP) is Sepro''s proprietary system for wet processing of fine incinerator bottom ash. Wet treatment is far superior to a conventional "dry" processing of IBA because it is much more effective for recovering valuable metals. The first step is to remove coarse material from the IBA using a jig or screen.

(57) [Summary] [Purpose] Reduction of steam aging cost for steelmaking slag. [Structure] Chemical analysis of slag generated from a steelmaking furnace is performed for each charge, and only slag with a low basicity is separately collected. This low basicity slag is steam-aged. [Effect] It is possible to obtain high quality slag that can be sufficiently used as a roadbed material at low cost.
