The production of ammonium metatungstate (AMT) typically involves several steps, each of which may require different equipment. Here is an overview of the equipment commonly used in AMT production:
Grinding and crushing equipment: Tungsten ore or concentrate is typically first ground and crushed to a fine powder using equipment such as ball mills or jaw crushers.
Mixing equipment: The powdered tungsten ore is mixed with ammonium hydroxide solution to form a slurry. This can be done using equipment such as mixing tanks or agitators.
Heating equipment: The slurry is then heated under controlled conditions to extract the tungsten and form an ammonium tungstate solution. This can be done using equipment such as heat exchangers, reactors, or evaporators.
Filtration equipment: The ammonium tungstate solution is typically purified by filtration to remove impurities. This can be done using equipment such as filter presses or vacuum filters.
Solvent extraction equipment: The purified ammonium tungstate solution may be further purified by solvent extraction to remove any remaining impurities. This can be done using equipment such as extraction columns.
Crystallization equipment: The purified ammonium tungstate solution is then subjected to controlled heating and evaporation to form ammonium metatungstate crystals. This can be done using equipment such as crystallizers or evaporators.
Separation and drying equipment: The AMT crystals are separated from the remaining solution, washed, and dried. This can be done using equipment such as centrifuges or vacuum dryers.
Overall, the production of AMT requires a range of specialized equipment to ensure consistent quality and purity of the final product. The specific equipment used may vary depending on the scale of production and the specific processing conditions required.
