PROBLEM TO BE SOLVED: To provide an abrasive capable of effectively separating and recovering it from the mixture with the abrasion waste of a material to be polished, and using it again, and a polishing method with the abrasive. SOLUTION: This method uses a abrasive having an average particle diameter in the range of 1<=d50<=80, a dispersion coefficient in the range of 1<=dx<=80, a sharpness of particle diameter in the range of 1<=d50/dx<=5, a hardness of Morse 1-12 in the range of 0<=(d90-d10)/d50<=10, and a magnetism in the range of 10<=dmax<=200 to polish an abrasion object, then the mixture of the abrasive and the abrasion waste of the abrasion object are separated into the abrasive and the abrasion waste of the abrasion object, and are recovered. |
