How To Extract Tungsten From Ore
Wolframite is a common tungsten ore whose main component is calcium tungstate (CaWO4). The main flow includes as follows: Crushing and grinding: The original wolframite ore is crushed and ground to make it smaller into smaller particles, which is convenient for subsequent beneficiation. Gravity separation: This process utilizes the density difference between …
