The sources of China's marble are mainly Shandong, Guangxi, Guangdong and Jiangsu, which contribute about 50% of the country's total supply, and marble can be supplied in large batches. The supply from Henan, Hubei, Yunnan and Sichuan takes up about 30% of the national total; the marble supplied by these provinces is of varying colors and patterns and some varieties belong to high-grade marble. The imported marble mainly comes from Italy (taking up 70% of the total imports) and Spain (10%) and other marble comes from Hongkong, Taiwan, Greece, India and Singapore.
Marble is generally used in interior decoration, whereas granite mostly in exterior decoration. The percentages of the marble application categories are as follows: outside pavement 8%; interior flooring 30%; exterior wall facing 10%; interior wall facing 15%; staircases 5%; architectural elements 8%; gravestone 10%; special engineering works 6%; others 8%.
As far as the marble production is concerned, China has ranked among the world's large producers, but from the grades, quality, batches and production scale of marble, as well as the overall technical level and economic performance, there still exists a rather big gap in comparison with countries with advanced levels in the world, and so does in comparison with granite in China's building stone industry. In order to achieve sustainable development of China's marble industry, make rational use of resources and change from a large resource country to a large producer, we need to attach importance to overcoming the following problems in China's marble industry.
First, we should strengthen mine construction. Marble is formed naturally and the existence of off-color, off-shade, color spots and color stripes is inevitable. For the application of marble, however, color hue consistency and harmony are required. To solve this contradiction, mines are required to have a certain industrial scale; thus quarry stone of different off-shades can be produced in batches and will not be mingled and the quality of the final products can be stable and meet the requirements of use and exports.As the professional manufacturer of complete sets of mining machinery, such as ore beneficiation,cement mill, Henan Hongxing is always doing the best in products and service.limestone rotary kiln:http://www.hxjq-crusher.com/23.html.ore separating line:http://www.hxjqchina.com/.
Efforts should be made to strengthen technical transformation. At present hand mining is still adopted in most marble mines of China. The equipment is backward and even the blasting method is used unrealistically, thus causing the destruction of mines and waste of resources. We should support and promote mechanical mining of marble mines. Only by using advanced technology and equipment, can large, regularly shaped and qualified blocks be quarried and can resources be developed in a protective way.
In order to achieve sustainable development of the marble industry, it is necessary to pay attention to environmental protection. Waste stone and tails produced during quarrying and processing can be utilized totally in making stone aggregates, stone grains, stone powder and various kinds of fillers, and industrial waste water can be recovered and clarified and used as circulating water.
So long as we make full use of the advantages of China's marble industry and overcome the existing problems gradually, China has conditions to rank among the world's large producers of marble in a relatively short period of time.
