Natural gypsum is the natural deposit of gypsum, mainly dihydrate gypsum and anhydrite. The reserves of gypsum mineral resources in China are about 57 billion tons, ranking the first in the world, distributed in 23 provinces, cities and autonomous regions, of which more than 1 billion tons are reserved. Conversely, Shandong, Inner Mongolia, Qinghai, Hunan, Hubei, Anhui, Jiangsu, Ningxia, Tibet, Sichuan and gypsum resources are relatively poor. Northeast China and East China.

　　我国石膏资源主要由普通石膏和硬石膏组成，其中硬石膏占总量的60%以上。高品位、一等品石膏作为一种优质资源，仅占总量的8%，其中纤维石膏仅占总量的1.8%。因此，我国是一个石膏储量大的国家，也是一个石膏质量较差的国家。优质石膏资源主要分布在湖北省应城市、荆门、衡山、湖南省、三水、山东枣庄、平陆县、山西省等地区。部分采场已接近枯竭，部分采场与低品位石膏难以分离，造成优质资源浪费。因此，中国高品质石膏资源的实际开采和利用较少。

　　China's gypsum resources are mainly composed of ordinary gypsum and anhydrite, of which anhydrite accounts for more than 60% of the total. As a kind of high-quality resources, high-grade and first-class gypsum only accounts for 8% of the total, and fibre gypsum only accounts for 1.8% of the total. Therefore, China is a country with large gypsum reserves and poor gypsum quality. High quality gypsum resources are mainly distributed in Yingcheng, Jingmen, Hengshan, Hunan, Sanshui, Zaozhuang, Pinglu and Shanxi provinces. Some stopes are nearly exhausted, and it is difficult to separate some stopes from low-grade gypsum, resulting in waste of high-quality resources. Therefore, the actual exploitation and utilization of high-quality gypsum resources in China is less.

　　我国石膏工业起步较晚，基础较差，但发展迅速。1995年，石膏产量猛增至2659万吨，超过美国，成为世界上大的石膏消费国。到2004年，石膏矿年产量超过3000万吨，石膏消费总量约3500万吨。我国石膏矿500多座，大中型石膏矿50多座，年产量10万吨以上，占总产量的40%左右，其中60%左右来自小城镇和农村。按生产方式，露天开采约占30%，地下开采约占70%。在地下开采石膏矿中，由于各种原因，平均开采率低于30%，以开采为主的优质资源没有得到合理开发和有效利用，资源浪费严重而痛苦!

　　The gypsum industry in China started late and had a poor foundation, but it developed rapidly. In 1995, the output of gypsum surged to 26.59 million tons, surpassing the United States and becoming the largest consumer of gypsum in the world. By 2004, the annual output of gypsum mines was over 30 million tons, and the total consumption of gypsum was about 35 million tons. There are more than 500 gypsum mines and more than 50 large and medium-sized gypsum mines in China, with annual output of more than 100,000 tons, accounting for about 40% of the total output, of which about 60% come from small towns and rural areas. According to the mode of production, open-pit mining accounts for about 30% and underground mining accounts for about 70%. In underground gypsum mining, due to various reasons, the average mining rate is less than 30%. The high quality resources mainly exploited by mining have not been reasonably exploited and effectively utilized, and the waste of resources is serious and painful.

　　使用广泛的天然石膏硬石膏,硫酸,其有效成分是钙二水物,通常根据内容分类的钙二水物矿硫酸。石膏应用领域广泛,产品种类较多,不同用途有不同的石膏原材料的质量要求,优质石膏用于特殊的石膏制品生产原材料,如食用、医疗、艺术、模型和化学填料;二水硫酸钙含量低于60%的石膏矿很少使用。超过60%的石膏矿被用于建筑材料和建筑等各个领域，这取决于石膏矿的含量。

　　The most widely used natural gypsum anhydrite, sulfuric acid, its active ingredient is calcium dihydrate, usually classified according to the content of calcium dihydrate mineral sulfuric acid. Gypsum is widely used in many fields, with many kinds of products and different quality requirements of gypsum raw materials for different purposes. High-quality gypsum is used to produce raw materials for special gypsum products, such as food, medicine, art, model and chemical fillers. Gypsum ore with calcium sulfate dihydrate content less than 60% is seldom used. More than 60% of gypsum ore is used in various fields such as building materials and construction, depending on the content of gypsum ore.

　　世界各国石膏消费结构不同。在发达国家，石膏深加工产品消费占很大比重，石膏产品消费结构占45%，水泥生产占45%，其他领域占10%。发展中国家特别重视矿石的初级应用，并依赖水泥工业。石膏产品的比重随着经济的发展而逐渐增加。我国的消费结构大致如下:水泥生产用缓凝剂占84%，陶瓷模具占6.5%，石膏制品和墙体材料占4.0%，化工等行业占5.5%;随着中国水泥产量的增加,对石膏的需求相应增加,与中国经济的快速发展同时,石膏行业特别是石膏产品将会有很大的发展空间,各种各样的石膏产品和石膏墙将得到高速发展,石膏的需求将上升,与传统陶瓷和其他特殊行业的发展,高质量的石膏资源不断减少,石膏资源的开发利用将越来越受到重视。因此，为了保证整个石膏行业的可持续发展，绿色、环保、健康的石膏建材和产品在人们的生活中得到更广泛的应用，有限的石膏资源必须得到优化利用

　　The consumption structure of gypsum varies from country to country in the world. In developed countries, the consumption of gypsum deep-processing products accounts for a large proportion. The consumption structure of gypsum products accounts for 45%, cement production accounts for 45%, and other fields account for 10%. Developing countries attach particular importance to the primary application of ores and rely on the cement industry. The proportion of gypsum products increases gradually with the development of economy. China's consumption structure is roughly as follows: cement retarder accounts for 84%, ceramic mould accounts for 6.5%, gypsum products and wall materials account for 4.0%, chemical industry accounts for 5.5%; with the increase of China's cement production, the demand for gypsum increases correspondingly, and with the rapid development of China's economy, gypsum industry, especially gypsum products, will have a great deal. The development space, a variety of gypsum products and gypsum walls will be developed at a high speed. The demand for gypsum will rise. With the development of traditional ceramics and other special industries, the high quality gypsum resources will decrease continuously. The development and utilization of gypsum resources will be paid more and more attention. Therefore, in order to ensure the sustainable development of the whole gypsum industry, green, environmentally friendly and healthy gypsum building materials and products are more widely used in people's lives. Limited gypsum resources must be optimized and utilized.
