<br /> Category Product o Applications
<br /> Secondary Titanium Minerals (Fe,Ti)203 a Titanium Metal Production:The primary use of titanium minerals is in the production of titanium Yes
<br /> (ilmenite,euxenite, (Y,Ca,Ce,U,Th)(Nb,Ta, metal,which is known for its high strength,light weight,and corrosion resistance.Titanium
<br /> columbite and rutile) Ti 2)0 6 metal is used in aerospace applications for aircraft components and space vehicles,as well as
<br /> Ti02 in military equipment.
<br /> • Pigments:Titanium dioxide(Ti02)is widely used as a white pigment in paints,coatings,
<br /> plastics,and paper due to its high refractive index,which gives it excellent light-scattering
<br /> properties.It provides whiteness and opacity to these products.
<br /> • Welding Rod Coatings:Titanium minerals are used in welding rod coatings,where they help
<br /> stabilize the arc during welding and improve the properties of the weld.
<br /> • Cosmetics and Sunscreens:Titanium dioxide is used in cosmetics and sunscreens due to its
<br /> ability to scatter ultraviolet(U\�light,providing protection from the sun's harmful rays.
<br /> • Aerospace and Defense:Due to its high strength-to-weight ratio and resistance to extreme
<br /> temperatures,titanium is used in various aerospace and defense applications,including aircraft
<br /> frames,engines,and armor plating.
<br /> • Medical Devices:Titanium's bio-compatibility makes it suitable for medical implants,such as
<br /> hip and knee replacements,dental implants,and surgical instruments.
<br /> • Desalination Plants:Titanium is used in desalination plants for its corrosion resistance,
<br /> particularly in parts exposed to seawater.
<br /> • Chemical Processing:In chemical processing industries,titanium is used for equipment such as
<br /> heat exchangers,reactors,and piping systems,especially in environments that are corrosive or
<br /> involve high temperatures.
<br /> • Automotive Applications:In high-end and performance vehicles,titanium is used for
<br /> components like exhaust systems and engine parts,leveraging its strength and light weight.
<br /> Secondary Garnet ([Mg,Fe,Mn]3AI2(SiO4)3 • Abrasive Blasting Media:Garnet is widely used as an abrasive blasting material for surface No
<br /> preparation in industrial painting and coating applications.Its hardness and angular shape
<br /> make it effective for removing rust,paint,and other coatings from metal,wood,and other
<br /> surfaces.
<br /> • Water-jet Cutting:Garnet is a preferred abrasive for water-jet cutting machines,which use
<br /> high-pressure water and garnet abrasives to cut a wide variety of materials including metal,
<br /> stone,glass,and composites.Its sharp edges and hardness allow for precise and efficient
<br /> cutting.
<br /> • Abrasive Powders:Garnet is ground into powders that are used as abrasives in sandpaper for
<br /> woodworking and automotive industries.It's used for finishing and polishing purposes due to its
<br /> effectiveness in smoothing surfaces.
<br /> • Filter Media:Garnet is used as a filtration media for both water and air filtration.Its chemical
<br /> stability and high specific gravity make it effective in filtering out contaminants.
<br /> • Water-jet Looms:In textile industries,garnet is used in water-jet looms for the efficient and
<br /> precise cutting of fabrics.
<br /> • Surface Preparation in Petrochemical Industries:Garnet is used for blast cleaning surfaces in
<br /> the petrochemical industry,preparing them for painting or coating.
<br /> • Grinding Media:In some applications,garnet is used as a grinding media.Its hardness makes it
<br /> suitable for grinding and sharpening metals.Abrasive materials
<br /> Secondary Magnetite Fe304 a Steel Production:Magnetite is a major source of iron,making it a crucial raw material in the No
<br /> production of steel.Its high iron content makes it a valuable ore for iron and steel industries.
<br /> Water treatment
<br /> • Coal Washing:Magnetite is used in the coal washing process.Its magnetic properties enable
<br /> the separation of coal from impurities.Coal particles are mixed with magnetite and water;the
<br /> mixture is then subjected to a magnetic field which separates the coal from heavier impurities.
<br /> • Dense Media Separation:In dense media separation processes,magnetite is used as a dense
<br /> medium.This is particularly common in mineral processing to separate minerals with different
<br /> densities,a method often used for separating diamonds from other material.
<br /> • Magnetic Resonance Imaging(MRI):Due to its magnetic properties,magnetite nanoparticles
<br /> are used as contrast agents in MRI scanning.
<br /> • Catalysis:Magnetite is used as a catalyst in certain chemical reactions,including the
<br /> production of ammonia in the Haber process.
<br /> • Electronics and Magnetic Storage:Due to its ferromagnetic nature,magnetite is used in
<br /> magnetic tapes and hard drives for data storage.
<br /> • Energy Storage:Research is being conducted on the use of magnetite in energy storage
<br /> systems and as a material for building lithium-ion batteries.
<br /> • Soundproofing and Insulation:Magnetite's density makes it useful for soundproofing and as an
<br /> insulating material in construction.
