how to separate two magnets？

There are two main ways to deep processing calcium carbonate, namely ultrafine pulverization and surface modification. Usually these two processes are done separately. In recent years, integrated deep processing technology of calcium carbonate has received increasing attention. The integrated process refers to surface modification while superfine pulverization.
  Calcium carbonate is one of the most widely used fillers, and is divided into light calcium and heavy calcium. Heavy calcium is widely used as a filler in industries such as rubber, paint, paper and plastics at an affordable price. With the development of modern composite technology, active calcium carbonate with various excellent properties has become an important functional enhancer and plays an increasingly important role in composite materials. In order to convert calcium carbonate from a general volume of filler to a functional filler, it must be further processed. There are two main ways to deep processing calcium carbonate, namely ultrafine pulverization and surface modification. Usually these two processes are done separately. In recent years, integrated deep processing technology of calcium carbonate has received increasing attention. The integrated process refers to surface modification while superfine pulverization.
