C22B34/1209 - CPC Classification

Classification description:

Obtaining refractory metals; Obtaining titanium, zirconium or hafnium; Obtaining titanium or titanium compounds from ores or scrap by metallurgical processing; preparation of titanium compounds from other titanium compounds  -  preliminary treatment of ores or scrap to eliminate non- titanium constituents, e.g. iron, without attacking the titanium constituent by dry processes, e.g. with selective chlorination of iron or with formation of a titanium bearing slag
