— Titanium is mainly extracted from two minerals—a dark brown to black rock with a crystal-like appearance called rutile, and ilmenite (titanium-iron oxide), a grayish-black rock. Other minerals that can also be refined to get pure titanium are anatase, perovskite, brookite, and titanite.

The transition from rutile to ferrouspseudobrookite of the major phase in slag contributed to this change. Side reactions, such as titanium and iron carbonization and silicon reduction, were effectively suppressed by the presence of FeO in the slag phase, thereby enhancing slag fluidity and purifying iron nugget during the smelting process.

The steps involved include extraction, purification, sponge production, alloy creation, and forming and shaping. ... hi need machinery to process 100tons per hour iron sand to remove titanium and seperate other contents if not you could you direct me to relevant company that deals with my ...

 — The production of raw titanium metal relies on natural and man-made feed materials, including natural rutile, titanium dioxide slags of different grades ("chloride slag," UGS, and "sulfate slag"), and synthetic rutile. Natural rutile was the feedstock of choice at the early years of the Kroll process, but nowadays it comes in limited ...

Under optimized conditions, after melting separation, the recovery rates of iron, titanium, vanadium, and chromium were 97.9, 89.8, 96.7, and 97.8%, respectively. Furthermore, …

 — Titanium is made by a batch process. In the production of iron, for example, there is a continuous flow through the Blast Furnace. Iron ore and coke and limestone are added to the top, and iron and slag removed from the bottom. This is a very efficient way of making something. With titanium, however, you make it one batch at a time.

 — The rising market demand for titanium products such as titanium dioxide, titanium alloys, and titanium metal draws more public attention to titanium ore processing. Titanium minerals are mainly from titanium rock ores and titanium placers. Titanite rock ores are mostly produced in the form of titanomagnetite-ilmenite. Major origins are Canada ...

A part of the sponge titanium, especially the sponge deposited near the reaction wall, is contaminated with iron, but the Kroll process can reliably produce titanium with a low oxygen concentration. In the Kroll process, titanium adheres at various points with the container, which implies that continuous titanium recovery is difficult.

 — This process extracts more titanium than iron but consumes more energy. As with weak acids, leaching in alkaline medium also extracts comparatively more titanium than iron, but requires an additional acid treatment step to obtain the final products. Particle size of ilmenite can be readily reduced via ball milling causing an enhanced ...

Nowadays titanium is manufactured by the Kroll process. First you heat titanium dioxide with carbon to about 1000 degrees C and pass chlorine over it. This makes TiCl4. People call that "Tickle". ...

 — Scraps originating from the Kroll process are iron-contaminated and cannot be used for producing titanium or its alloys (10–20% of total sponge production) . Indeed, during every melting process, iron (present in the steel reactor) diffuses into the titanium sponge, leading to the formation of impurities.
