Methodological Approaches to Development of Ecologically Safe Usage Technologies of Ferrous Industry Solid Waste Resource Potential

At the present day in Russia the change of ferrous metals production technology results in the change of the chemical composition of solid waste from iron and steel works. Traditional approaches to waste recycling methods stop meeting the requirements of geoecological safety. The paper offers a methodology of usage of the ferrous industry waste taking into consideration a life cycle of the materials, which comprise the ferrous industry waste. New methodological approaches to evaluate the technologies of waste recycling have been developed. Complex selection criterion for usage technologies of ferrous industry solid waste resource potential is developed taking into consideration ecological, technological and economical factors. A technology of ferrovanadium waste utilization as a free-running material at a solid domestic waste landfill is shown. Data on vanadium migration activity to model mediums is represented. Distilled water and acetated-ammonium buffer were used as model mediums. A laboratory unit was offered to model vanadium migration to filtrate at the solid domestic waste landfill. The obtained data shows sorption capacity of solid domestic waste. Vanadium content in the filtrate of the laboratory unit equals to 0,057 mg/l., which is equivalent of satisfactory figure of maximum permissible concentration.
