Study on Process of Nb and Ti Separation and Extraction from Nb and Ti Rich Sulfuric Acid Solution AITranslate
Abstract AITranslate
The process was studied of Nb and Ti separation and extraction from Nb and Ti rich sulfuric acid solution with 7.84g/L Nb2O5 and 47.40g/L TiO2.Titanium was precipitated from the Nb and Ti rich sulfuric acid solution by ammonium sulfate precipitation.When the enrichment ratio is 2.5,ammonium sulfate dosage is 450g/L,precipitation time is 90 min,calcination temperature is 900℃and time is 90 min,industrial titanium dioxide with more than 93.4% TiO2 is obtained,and Ti total recovery rate is more than 95.19%.Niobium was precipitated from the titanium-precipitated solution by calcium carbonate neutralization-ammonia precipitation.When the neutralized solution pH value is about 1.0,the niobium-precipitated solution pH value is about 5.0,calcination temperature is 800℃and time is 60 min,niobium oxide concentrate with an average Nb2O5 content of 30.51%is obtained,and Nb total recovery rate is over 98.9%.
