The U.S. Bureau of Mines (Piga et al. 1993) used a process of reduction roasting and magnetic separation to recover aluminum, iron, and titanium. Its process: bauxite residue, limestone, sodium carbonate mixed with coal, ground and reduction roasting at 800–1000°C, sintered blocks crushed and dissolved with water, 89% of the …

Approximately, 80 kt of titanium mill products was consumed by the aircraft industry in 2015, [ 72] and the major alloy was Ti 6-4. This alloy exhibits high specific strength and has a large capacity for impurities such as iron and oxygen. Hence, Ti 6-4 is a suitable alloy for titanium recycling by remelting.

The Kroll Process is comprised of 6 steps to produce the titanium we have come to use and benefit from: Step 1: The pure titanium ore is converted into a sponge through conducting an electrical charge through the ore. This is done in a chlorinator. Chlorine gas is then passed through the charge. Step 2: The titanium tetrachloride that is the ...

The Kroll Process. Regardless of the final usage titanium must first be removed from its ore and turned into pure titanium. This is done by processing titanium oxide manufactured from either ilmenite or rutile though the Kroll process. The output is a titanium sponge which is purified, melted and alloyed with other metals.
