Marble Quarrying Technology Introduction To You

Marble discovered in China up to now includes more than 400 varieties

. In this respect, even countries with the developed marble industry such as Italy cannot compare with China. More than 100 varieties of marble that have been coded by the foreign trade department can be exported in batches.Marble with varying colors and patterns has formed a series. There are all kinds of colors, e.g. white, black, red, gray, green, yellow and flesh-red, and all kinds of patterns, e.g. misty, landscape-shaped, whorl, willow-leaf, spotty and rare paleontological fossil patterns. The great majority of China"s marble varieties are of good quality. Their fine and even texture, elegant hues, beautiful patterns, attractive luster and good decorative and use performances can attain related standards and requirements, and many varieties are welcome by users on the domestic and overseas markets and enjoy certain popularity. Marble with explored reserves is mainly of medium grade and less commonly of high grade. The marble varieties, e.g. "white marble", "Dandong green" and "rosin yellow" are greatly welcome by users, but they are difficult to quarry because they have only small reserves and have been quarried for a long time. Particularly, white, pure black and light-co-lored marble that has long sold well on the international markets is rather deficient in terms of the quantity and quality.As the professional manufacturer of complete sets of mining machinery, such as cement production line,sand washing machine, 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/. Conditions of development and utilization Marble occurrences of China are mainly distributed in the eastern and central parts. The eastern region generally has better conditions of development and utilization of marble resources because of relatively developed economy and convenient traffic. The eastern and central regions are major producers of commodity marble. There are several high-quality marble deposits in southwestern China, but they are difficult to develop on a large scale in a short time because they are located in outlying areas where mountains are high and roads are perilous, mining conditions are poor and especially the transport cost is too high. The high-quality varieties are, for example, "emerald green in snow" at Fugong, "Yunyang crystal white" and "Yunyang ice flower" at Yunyang and "Pingbian white" at Pingbian in Yunnan Province, and "Shimian white" at Shimian and "white marble" at Xiaojin in Sichuan Province.artificial sand maker:http://www.hx-china.com/8.html flotation machine:http://www.hxjqchina.com/product-list_49.html
