Question

Which of the titanium-containing minerals rutile (TiO2) or ilmenite (FeTiO3) has the larger percentage of titanium?

Answer 1

Both rutile (TiO2) and  ilmenite (FeTiO3) has the equal percentage of titanium.

Explanation:

• Titanium dioxide has the equal percentage of rutile and ilmenite. It's molecular weight is 79.87 gram per mole. Titanium oxide is a naturally occuring element produced from rutile,ilmenite and anatase.
• These minerals combine and form titanium dioxide. It will be used in many applications. It will be used in many chemical reactions.
• Titanium has a ph percentage of 7.5. It has a correct level of ph. So both has a equal level of titanium.

                                     

Answer 2

Rutile (TiO2) or ilmenite (FeTiO3) titanium-containing minerals  has the larger percentage of titanium is explained below.

Explanation:

1. Titanium is obtained from different ores that occur naturally on the Earth. Ilmenite (FeTiO3) and rutile (TiO2) are the most important sources of titanium.

2. According to USGS, Ilmenite(FeTio3) accounts for about 92% of the world’s consumption of titanium minerals.

3. World resources of anatase, ilmenite and rutile total more than 2 billion tonnes. Identified reserves total 750 million tonnes (ilmenite plus rutile).

4. China, with 20 million tonnes--accounting for 29% of the world total-- is now the country that is most abundant in terms of ilmenite reserves. Meanwhile, Australia, with 24 million tones rutile reserves—accounting for 50% of the world total—is now the country that is most abundant in terms of rutile reserves.

5.Ilmenite can be mined from both layered intrusive deposits and heavy mineral deposits. It is often found alongside rutile in heavy mineral deposits. Ilmenite is used to make titanium dioxide  pigment or it can be processed into feedstock that can be used in the manufacture of titanium. This has become more common as viable rutile deposits become increasingly scarce. South Africa and Australia are among the world’s largest producer of Ilmenite, each extracting over a million metric tonnes per year.

6.The Mining of titanium from intrusive rock is restricted to ilmenite and its weathered derivative leucoxene. The largest opencast ilmenite mine is Tellnes in Norway’s municipality of Sokndal.
