- W2596235300 abstract "In metallurgical sludge of JSK “Chusovoy Metallurgical Works” contains a high percentage of manganese compounds, iron, titanium, vanadium, calcium, magnesium, and others. Under the influence of precipitation of the metal ions are washed out of the metallurgical waste, which is a serious environmental problem for the environment. Reduce the negative impact of the metallurgical enterprise on the environment is possible by recycling steel waste. In particular, the article presents the results of laboratory studies of the process of extraction of manganese ions from metallurgical sludge sulfuric acid solution. Efficiency of the process of extraction of manganese ions was evaluated by potentiometric method. The original chemical composition of the waste leaching analyzed by spectroscopy at atomic emission spectrometry with inductively coupled plasma Optima-3000 firm “Perkin Elmer”, USA. The experimental results showed that when 50 % sulfuric acid concentration and the time duration of the dissolution process intensive hydrodynamic regime removed the greatest possible quantity of manganese in the solution. Using a thermodynamic analysis of the dissolution of manganese oxide solutions of sulfuric acid, as well as on the basis of literature data determined the optimum leaching temperature. The obtained results of the study allowed to establish optimal technological parameters of the process of manganese ions leaching of sulfuric acid solutions and confirmed the possibility of extracting manganese ions from metallurgical waste of JSK “Chusovoy Metallurgical Works” in order to get popular on the Russian market of manganese compounds." @default.
