Dopo disgregazione del minerale con perossido di sodio e insolubilizzazione della silice, si separa il ferro con idrogeno solforato in soluzione alcalina contenente acido tartarico, indi si precipita il titanio con cupferron in soluzione acida, si filtra, si calcina e si pesa infine l' ossido di titanio. Se il minerale contiene zirconio o vanadio è necessario purificare l' ossido di titanio. Soluzioni e reattivi. Procedimento. Prova in bianco. Calcolo.
