It is common that a partially refined chemical such as ammonium paratungstate (APT) will be sold and shipped for further processing, rather than shipment of raw ore itself.
Extracting the tungsten means also separating the tungsten from other metallic cations in the ore. This is a multistep process, but in very simple terms, it looks like this: Pulverize tungsten ore to make very small particles, then make a slurry manipulate pH to remove impurities Contact WO3 solution with NH3 to form Ammonium ParaTungstate (APT)Beneficiation of tungsten ores in India: A review,Tungsten ore deposits can consist of simple wolframite, simple scheelite or a wolfra mitescheelite combination. step after crushing and grinding of the ROM ore, followed by processing the pre concentrate, concentrate cleaning or upgradation step, and a final purification stage to meet the market specifications.Where tungsten is found?
