The extracted fluorite is first crushed by the main jaw crusher in the beneficiation equipment. After crushing to a reasonable fineness, the fluorite is evenly fed into the ball mill through the hoist and the ore feeder to crush and grind the fluorite. The fine ore grinded by ball mill enters the next process classification.
Jul 29, 2020 Ore washing is the simplest and most effective method to improve the bauxite aluminum-silicon ratio by about 2 times. But you need to combine the ore washing process with other methods including classification -Manual selection process. Complete process Step 1 Use stone crushers to crush the primary bauxite then make a further grinding.
