Development Patterns Of Sea Salt In Great China

China"s salt resources show a basic distribution pattern of sea salt resources in the easte-rn part

, lake salt resources in the western part, and well salt and mineral salt resources in the middle part. (1) Sea salt resources China"s sea salt resources are mainly distributed in the eastern coastal areas. China has a long coastline, which stretches for 18,000 km from the Yalu River estuary, Liaoning Pro-vince in the north through to the Beichang River mouth, Guangxi Zhuang Autonomous Region in the south, involving 11 provinces (autonomous regions and municipalities). Should the coastline of offshore islands be included, the total length of China"s coastline would reach 21,000 km. The principal coast type of the Chinese continent is the plain coast, which is favorable for drawing water from the sea to make salt. By the end of 1997, beach salterns of 43.45 km2 had been built. They constitute two sea salt zones: northern and southern. The northern zone, the principal sea salt producing zone, consists of the salt fields in 5 provinces (municipalities): Liaoning, Hebei, Tianjin, Shangdong and Jiangsu, which have an aggregate area of 38.75 km2, making up 89.18% of the total area of China"s saltfields. Among these saltfields, those in Shandong are the largest in area, accounting for 30.52% of the aggregate area of the saltfields in the northern sea salt zone, while the saltfields in Jiangsu and Hebei comprise 23.22% and 21.55%, respectively. The important saltworks in this zone are the Yingkou Saltworks in Liaoning, the Fuzhouwan Saltworks in Dalian, the Tanggu Saltworks in Tianjin, the Nanbao Saltworks in Hebei, the Jiangsu Salt Industry Company, etc. The southern sea salt zone involves Zhejiang, Fujian, Guangdong and Hainan Provinces and the Guangxi Zhuang Autonomous Region, with an aggregate area of saltfields reaching 4.70 km2, whichconstitute only 10.82% of the country"s total area of saltfields. In the southern sea salt zone, the saltfields in Zhejiang, Fujian and Guangdong are the major producers. The large-sized salterns in the southern zone include the Yinggehai Saltern in Hainan and the Putian Saltern in Fujian. Besides, there also exist saltfields in Tunghsiao, Lukang, Peimen, Hsikang and Tainan along the west coast of Taiwan Province.As the professional manufacturer of complete sets of mining machinery, such as mobile crushing station,sand washer, 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/. (2) Salt mineral resources By the end of 1997 China had verified 151 mineral occurrence localities of salt, including those of lake salt, brine and rock salt and owned retained NaCl reserves of 384,339 million tons and ore reserves of 20,643 million tons. These reserves are widely distributed in 18 provinces (regions). Among them, Qinghai, Jiangxi, Hubei, Yunnan and Sichuan are pro-vinces, each of which is possessed of NaCl reserves exceeding 10,000 million tons China is very rich in salt resources. It has not only abundant sea salt resources but huge, densely distributed saline lakes and numerous underground brine and rock salt deposits with plentiful reserves.limestone rotary kiln:http://www.hxjq-crusher.com/23.html stone jaw crusher:http://www.hxjq-crusher.com/17.html
