In general, the mining of granite is made of wire sawing. There are new technologies such as dense drainage and flame injection. Flame spray method of mining stone cutting neat, no injury, high production efficiency. Pick stones with coarse whole called blocks, followed by artificial drilling or sawing machine to carve, prepared bulk, plates with required size; milling machine or lathe machining, a cylindrical or arc shape; the artificial cut coarse and fine grains of rock drilling, grinding, or by machine the surface polishing, crystal clear. Granite does not pollute the environment. Synthetic materials are often accompanied by bad or even toxic by-products, which need to be replaced several times during the construction period. Granite does not need to be replaced because it is very durable.

In addition, granite is very practical and can be made into a variety of surfaces - polishing, sublight, and fine.Since granite is often contained in radioactive materials, it is necessary to measure the level of radiation when using granite and reconfirm its use.

Eight methods for stone surface treatment:

Polishing: high gloss on the surface. The polishing may last for a long time or not, mainly to see the type of stone. Granite, Dali, and limestone are usually polished and need different maintenance to keep their luster.

Matt: polished surface looks very soft, obvious scratches, without too much care. Marble, limestone and slate are suitable for polishing.

Pickling: there are small corrosion marks on the surface. The surface of the acid is less scratched, and the appearance is more simple than the surface of the polished surface. Most of the stones can be pickled, but the most common are marble and limestone. Acid pickling is also a way to soften the gloss of granite.

Chiselled (Axe chopping): the surface is not smooth. After initial cutting, the stone is processed to eliminate obvious scars, but the effect is not up to the ground after effect. Granite, marble, and limestone can be treated in this way, usually in a custom-made case.

Flamed: rough surface. The surface is mainly used as a floor or as an ornamental surface for commercial building, with a higher labor cost. The burning surface is formed by rapid cooling after high temperature heating. The surface of the fire is usually granite.

Crack: rough surface, but not as rough as fire. This surface treatment is usually used in mine hand cut or crack chisel to expose the natural stone surface. This surface treatment is mainly used for slate.

Tumbled: smooth or slightly rough surface, smooth and broken edge angle. There are several ways to achieve the roll effect. 20 millimeter bricks can roll in the machine, and 3 centimeters of bricks can be rolled up and split into two blocks. Marble and limestone are the first choice for rolling.

Brushing: the surface is old and old. The treatment process is to brush the surface of the stone and imitate the natural wear effect of the stone.
