硫酸盐矿物是金属元素阳离子（包括铵根）和硫酸根相化合而成的盐类。下面和小编一起来看看几种重要的硫酸盐都有哪些：
　　Sulfate minerals are salts formed by the combination of metal cations (including ammonium radicals) and sulfate radicals. Now let's take a look at some of the most important sulfates.
　　1、硫酸钙
　　1. Calcium Sulfate
　　自然界中的硫酸钙以石膏矿的形式存在。含有两个结晶水的硫酸钙（CaSO4·2H2O）叫做石膏（也叫生石膏）。将石膏加热到150℃，就会失去大部分结晶水而变成熟石膏（2CaSO4·H2O）。熟石膏与水混合成糊状后会很快凝固，转化为坚硬的生石膏。利用石膏的这一性质，人们常利用它制作各种模型和医疗上用的石膏绷带。在水泥生产中，可用石膏调节水泥的凝固时间。在石膏资源丰富的地方可以用它来制硫酸。
　　Calcium sulfate in nature exists in the form of gypsum ore. Calcium sulfate (CaSO4. 2H2O) containing two crystalline waters is called gypsum (also known as raw gypsum). When gypsum is heated to 150 C, it loses most of its crystalline water and becomes mature gypsum (2CaSO4 H2O). When hydrated gypsum is mixed with water, it solidifies quickly and turns into hard raw gypsum. Using this property of gypsum, people often use it to make various models and plaster bandages for medical use. In cement production, gypsum can be used to adjust the setting time of cement. It can be used to produce sulphuric acid where gypsum resources are abundant.
　　2、硫酸钡
　　2. Barium Sulfate

　　天然的硫酸钡称为重晶石，它是制取其他钡盐的重要原料。硫酸钡不容易被X射线透过，在医疗上可用作检查肠胃的内服药剂，俗称“钡餐”。硫酸钡还可以用作白色颜料，并可做油漆、油墨、造纸、塑料、橡胶的原料及填充剂。
　　Natural barium sulfate is called barite. It is an important raw material for making other barium salts. Barium sulfate is not easily transmitted by X-ray. It can be used as an oral medicine for examining the intestines and stomach in medicine, commonly known as "barium meal". Barium sulfate can also be used as white pigments and as raw materials and fillers for paints, inks, papermaking, plastics and rubber.
　　3、硫酸亚铁
　　3. Ferrous sulfate
　　硫酸亚铁的结晶水合物俗称绿矾（FeSO4·7H2O）。在医疗上硫酸亚铁可用于生产防治缺铁性贫血的药剂，在工业上硫酸亚铁还是生产铁系列净水剂和颜料氧化红铁（主要成分为Fe2O3）的原料。
　　The crystalline hydrate of ferrous sulfate is commonly known as alum (FeSO4.7H2O). Ferrous sulphate can be used in medicine to prevent and cure iron deficiency anemia. Ferrous sulphate is also used in industry as raw material to produce iron series water purifier and red iron oxide (the main ingredient is Fe2O3).
