Tantalum and niobium,
tantalum and niobium ore แtntaalts Oclamabts come together in a common source: It is found in the slag by smelting tin production: Thailand is producing tantalum powder and niobium oxide Payne Payne Ta Ta oxide of tin slag one. By the tin slag grinding it out and then dissolved with a mixture of hydrofluoric acid, Oregon with sulfuric acid 2. Then add methyl iso-butyl ketone into the compound of the Las alums and niobium are dissolved in a layer of methyl iso-butyl ketone 3. The separation of methyl iso-butyl ketone out four. Then add sulfuric acid to the niobium is dissolved in dilute acid class of five. Once a separate class of acid solution and the solution with ammonia to neutralize the sludge 6. When the burn will occur niobium oxide Ta Payne 7. The layer of tantalum soluble in methyl iso-butyl ketone. Separated by passing steam into the tantalum is dissolved in water in the form of a class of compounds H2TaF7 8. When adding a solution of potassium chloride is then crystallized substance. K2TaF7 which to exploit the mineral extraction *** The slide is at Columbine. Before discharge into the environment had to get rid of contaminants. And pretreatment effluent to neutral. In addition, tin slag There may be radioactive Such as uranium and thorium are present. To determine the amount of radioactive material is a lot more than the benchmark amount tantalum metal melting point of 2996 degrees Celsius properties: a silver gray metallic fireproof. The hardness and toughness similar to steel brings benefits: - use electronic devices in the computer. Communication tool Kanpai transmitter Timer - High heat-resistant alloy for making some of the fuselage - made head of ballistic missiles. Equipment in atomic reactors - the tantalum oxide coated lenses for a property to reflect light better properties of the metal niobium melting point 2487 ° C: - metal niobium has a silver gray - hardness and toughness similar to copper - conductors. heat and electricity better Ease of processing It used to make alloys with special properties such as pressure, toughness is rust - corrosion resistance and conductivity at low temperatures - is also used in electronics. Nuclear Equipment Parts of aircraft and missiles
