It is a rare and strategic metal for the electronics industry with limited substitutability. Tantalum is a metallic element with outstanding heat resistance, high electrical capacitance and very high resistance to corrosion and chemical intrusion. This element is vital for the electronics industry. Its primary use is in the form of powder for the manufacture of capacitors used in cell phones, computers, TV screens, digital cameras and other electronic equipment. On the other hand, in the form of metal, it is used, for example, in the manufacture of jet turbine blades, missile parts and nuclear reactors. Brazil occupies a prominent position in the world scenario of tantalite mining, either as a reserve holder or as a producer; and the medium-term outlook for the tantalite market is one of relative scarcity and significant price increases. The total Brazilian reserves represent about 68% of world reserves.
Introduction Bentonite Mat are consisting of three different layers supported by geotextiles and/or geomembranes, mechanically held together by needling, stitching, or chemical adhesives. A Bentonite Mat construction would consist of two layers of Bentonite Mat stitched together enclosing a layer of natural or processed sodium bentonite. The engineering function of a Bentonite Mat is containment as a hydraulic barrier to water, leachate or other liquids and sometimes gases. Typical Applications Includes Ponds and stormwater impoundments: Bentonite Mat are widely implied in sewage reservoir, storage ponds, and regular reservoir. The Bentonite Mat does not require specialized machine nor skilled workers, which makes it a great material for ecological pool protection. Landfill liner : Bentonite Mat can replace the clay layer of geosynthetic membrane compound system, offering less systematic leakage rate. For a better result,combining with geosynthetic membrane is recommended. By doing so, when the geomembrane is compromised, the Bentonite Mat can still work for its purpose. Anti-leakage of gas or oil depot:Due to the ease of application and great toughness, it is the most economic and reliable choice of leakage protection for oil or gas depot. Landfill cap: Using the Bentonite Mat are widely adopted in different countries, for the damage and crack effect of uneven subsidence, desiccations, and dampness are drastically less than ordinary clay layer. Hence, the Bentonite Mat are extraordinary suitable for landfill cap. Underground project waterproofing: The protruding thin fibers of Bentonite Mat surface can lodge in concrete and served as an anchor. When the subsidence occurs, the small anchors would prevent the Bentonite Mat and structure from forming a water intrusion interface.

Fly ash is a by-product of coal burning at the utility plants. As coal is burned, non-combustible mineral impurities in coal evaporate and condense into tiny particles of glass, almost totally spherical in shape. The individual particles are very small, like talcum powder and are carried up and out of the boiler in the flow of exhaust gases leaving the boiler after the coal is consumed. The fly ash particles are removed from the exhaust stream in bag houses or electrostatic precipitators and then stored for later shipment The difference between fly ash and Portland cement becomes apparent under a microscope. Fly ash particles are almost totally spherical in shape allowing them to flow and blend freely in mixture. That capability is one of the properties making fly ash a desirable admixture of concrete.

Vanadium nitrogen alloy is a new alloy additive which can replace ferro vanadium for the production of microalloyed steel. NiV can improve the mechanical properties of steel such as strength, toughness, ductility and thermal fatigue resistance,and make the steel have good weldability. At the same strength,use NIV can save vanadium addition20-40%,thereby reducing the cost. NiV alloy can be used in structural steel, tool steel, pipeline steel, reinforcing bar and cast iron. Vanadium-nitrogen alloys can be effectively microalloyed simultaneously in high strength low alloy steels to promote the precipitation of carbon, vanadium and nitrogen compounds in steels,more effectively enhance sedimentation and grain refinement
Magnesite (Raw)
Feldspar is a common raw material used in glassmaking, ceramics, and to some extent as a filler and extender in paint, plastics, and rubber. In glassmaking, alumina from feldspar improves product hardness, durability, and resistance to chemical corrosion. In ceramics, the alkalis in feldspar (calcium oxide, potassium oxide, and sodium oxide) act as a flux, lowering the melting temperature of a mixture.
