Due to the significant differences in the material of different types of marble, the processing method should be selected based on the differences in the characteristics of each variety of marble.

　　Marble with a high content of calcium and magnesium carbonate or cracks and holes can be corroded by soaking in hydrochloric acid for about 10-20 minutes (depending on the specific type of stone); Afterwards, use a steel brush to remove the residue from cracks and holes to increase the three-dimensional effect of the stone surface. Finally, use a grinding brush from coarse to fine grit to polish the surface in sequence until the surface meets the customer's required gloss.

　　If the marble has a lot of calcite, it can be directly processed with a steel brush. Similarly, the uneven three-dimensional surface effect can be first brushed with a steel wire brush, and then the grinding brushes from coarse mesh to fine mesh can be used in sequence for polishing. Usually, 180 #, 240 #, 320 #, and 500 # grinding brushes are used for processing. If the texture of the marble is relatively hard, the first few steps can be added appropriately.
