| titleOfInvention | Method of titanium extraction from slag obtained during cast iron and steel production out of titanomagnetite concentrate |
| abstract | FIELD: metallurgy. n SUBSTANCE: invention relates to the method of titanium extraction from slag obtained during cast iron and steel production out of titanomagnetite concentrate. The method means grinding and sulphuric leaching of the slag with metals movement from the slag to the sulphuric solution in form of sulphates. The metals (Me) are deposited from the obtained sulphuric solution by magnesium oxide and (or) hydroxide in form of Me(OH) n using the sodium hydroxide NaOH for magnesium hydroxide regeneration and turnover, by calcium hydrate use for sodium hydroxide regeneration, its turnover, and synthesis of precipitating gypsum. The titanium extraction from the sulphuric solution is performed in form of precipitation of the titanium oxy hydroxide TiO(OH) 2 obtained during reaction of titanium sulphates with magnesium oxide and (or) hydroxide at pH from 0 to 2.0 at stoichiometric ratio water:sulphuric acid = 1:1.63 to achieve maximum temperature of the solution 125°C and maximum thermal effect 84 kJ/mol. n EFFECT: reduced cost for energy carriers and intensification of the titanium extraction from slags with different composition. n 3 cl |
