Disclosed is a method for purifying a whisker stone by a magnetic filter. In the method, a whisker stone is milled by a material including 1 Kg/ton of Sodium Silicate. Next, the whisker stone is mixed with a polishing liquid whose density is about 25 % during 30 minutes. The pausing time is 30 minutes to the extent of 3 hours. Next, a magnetic filtering is performed in 8 KG magnetic force by the Metal Fine Wool Fiber magnetic filter. Next, the whisker stone is mixed during 30 minutes. The pausing time is 10 minutes to the extent of 30 minutes. And the 2nd separation process is performed to the whisker stone. Thereby, the purifying quality is improved as a result of the magnetic filtering and 2nd separation process.
