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.

　　我國石膏資源主要由普通石膏和硬石膏組成，其中硬石膏占總量的60%以上。高品位、一等品石膏作為一種優(yōu)質(zhì)資源，僅占總量的8%，其中纖維石膏僅占總量的1.8%。因此，我國是一個石膏儲量大的國家，也是一個石膏質(zhì)量較差的國家。優(yōu)質(zhì)石膏資源主要分布在湖北省應城市、荊門、衡山、湖南省、三水、山東棗莊、平陸縣、山西省等地區(qū)。部分采場已接近枯竭，部分采場與低品位石膏難以分離，造成優(yōu)質(zhì)資源浪費。因此，中國高品質(zhì)石膏資源的實際開采和利用較少。

　　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.

　　我國石膏工業(yè)起步較晚，基礎較差，但發(fā)展迅速。1995年，石膏產(chǎn)量猛增至2659萬噸，超過美國，成為世界上大的石膏消費國。到2004年，石膏礦年產(chǎn)量超過3000萬噸，石膏消費總量約3500萬噸。我國石膏礦500多座，大中型石膏礦50多座，年產(chǎn)量10萬噸以上，占總產(chǎn)量的40%左右，其中60%左右來自小城鎮(zhèn)和農(nóng)村。按生產(chǎn)方式，露天開采約占30%，地下開采約占70%。在地下開采石膏礦中，由于各種原因，平均開采率低于30%，以開采為主的優(yōu)質(zhì)資源沒有得到合理開發(fā)和有效利用，資源浪費嚴重而痛苦!

　　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.

　　使用廣泛的天然石膏硬石膏,硫酸,其有效成分是鈣二水物,通常根據(jù)內(nèi)容分類的鈣二水物礦硫酸。石膏應用領(lǐng)域廣泛,產(chǎn)品種類較多,不同用途有不同的石膏原材料的質(zhì)量要求,優(yōu)質(zhì)石膏用于特殊的石膏制品生產(chǎn)原材料,如食用、醫(yī)療、藝術(shù)、模型和化學填料;二水硫酸鈣含量低于60%的石膏礦很少使用。超過60%的石膏礦被用于建筑材料和建筑等各個領(lǐng)域，這取決于石膏礦的含量。

　　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.

　　世界各國石膏消費結(jié)構(gòu)不同。在發(fā)達國家，石膏深加工產(chǎn)品消費占很大比重，石膏產(chǎn)品消費結(jié)構(gòu)占45%，水泥生產(chǎn)占45%，其他領(lǐng)域占10%。發(fā)展中國家特別重視礦石的初級應用，并依賴水泥工業(yè)。石膏產(chǎn)品的比重隨著經(jīng)濟的發(fā)展而逐漸增加。我國的消費結(jié)構(gòu)大致如下:水泥生產(chǎn)用緩凝劑占84%，陶瓷模具占6.5%，石膏制品和墻體材料占4.0%，化工等行業(yè)占5.5%;隨著中國水泥產(chǎn)量的增加,對石膏的需求相應增加,與中國經(jīng)濟的快速發(fā)展同時,石膏行業(yè)特別是石膏產(chǎn)品將會有很大的發(fā)展空間,各種各樣的石膏產(chǎn)品和石膏墻將得到高速發(fā)展,石膏的需求將上升,與傳統(tǒng)陶瓷和其他特殊行業(yè)的發(fā)展,高質(zhì)量的石膏資源不斷減少,石膏資源的開發(fā)利用將越來越受到重視。因此，為了保證整個石膏行業(yè)的可持續(xù)發(fā)展，綠色、環(huán)保、健康的石膏建材和產(chǎn)品在人們的生活中得到更廣泛的應用，有限的石膏資源必須得到優(yōu)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.
