Many nonferrous metals, rare metals, precious metals and nonmetallic minerals are genetically related to marble. It is also an excellent building material and raw material for fine arts and crafts. Marble is of medium hardness and easy to be mined and processed. The polished plate presents decorative patterns or color textures, which are very beautiful and can be used as indoor and outdoor decorative materials. The wastes in mining and processing can be made into handicrafts or crushed into high-quality aggregates for the production of terrazzo, brush stone, etc. A few highly dense and homogeneous materials can be used for artistic carving and decoration. Because marble is basically composed of pure calcium carbonate or magnesium carbonate, it is extremely sensitive to the dissolution of acid polluted air. There are usually carbonic acid separated from carbon dioxide and sulfuric acid generated from smoke in the urban atmosphere. They are constantly in contact with marble, which affects marble supplies to varying degrees. In any case, marble is still an ideal material for architectural decoration and sculpture.
