There are two types of titanium ore with mining value in the world: primary ore and placer ore. Raw cattle ores are basically symbiotic minerals, including different types such as ilmenite, titanium magnetite and hematite.

Primary ore is characterized by concentrated production areas, large reserves, and can be mined on a large scale. Its disadvantages are dense structure, low mineral processing recovery rate, and low concentrate grade.

It is mainly concentrated in Canada, Navigation, China, India, and Russia. Placer deposits are aquatic minerals deposited on coasts and riverbanks.

The main iron minerals in placer mines are ilmenite and rutile, which are often symbiotic with monazite, stoutite, cassiterite, etc. The advantages are loose structure, easy mining, good dissociation of titanium mineral monomers, good selectivity, and precision.

The mineral grade is high, but the disadvantage is that the resources are scattered and the raw ore grade is low. It is mainly produced in the coastal and inland sedimentary layers of South Africa, Australia, India and South American countries.

It is 28230000.

Polypropylene and fiberglass are distinct materials, each with unique properties and applications. Polypropylene is a type of thermoplastic polymer, known for its versatility, chemical resistance, and being used in various industries for products such as containers, textiles, and automotive parts. On the other hand, fiberglass is a fiber-reinforced plastic where glass fibers are the reinforcement. It is famous for its strength, durability, and lightweight properties, making it ideal for construction, automotive, and marine applications. Although both materials are used in composite forms for enhanced characteristics, they are fundamentally different substances and not interchangeable. They can, however, be combined in certain composite materials to exploit both materials' advantages.
