Sulfate mineral | Types, Properties & Uses | Britannica
网页Sulfate mineral, any naturally occurring salt of sulfuric acid. About 200 distinct kinds of sulfates are recorded in mineralogical literature, but most of them are of rare and local occurrence. Abundant deposits of sulfate minerals, such as barite and celestite, are exploited for the preparation of.
Sulfate mineral - Wikipedia
网页The sulfate minerals are a class of minerals that include the sulfate ion (SO2−. 4) within their structure. The sulfate minerals occur commonly in primary evaporite depositional environments, as gangue minerals in hydrothermal veins and as secondary minerals in the oxidizing zone of sulfide mineral deposits.

网页2022年8月28日 · Mineralogists divide sulfate minerals into two groups: the anhydrous sulfates and the hydrous sulfates. Chemistries and structures of the anhydrous sulfates are related to the carbonates with SO 4 replacing CO 3. More than 100 sulfate minerals are known, and most are rare. Gypsum and anhydrite are the only rock-forming sulfates.

网页2018年1月1日 · Sulfate minerals are mineral species in which the dominant anionic entity is the sulfate anion, [SO 4] 2− (Chang et al. 1996; Alpers et al. 2000). About 380 valid species of sulfate minerals had been described by early 2017 (cf. www.mindat.org ), which are often grouped into a broader “sulfate” anion class along with the much small number ...
7.4.4: Sulfate Minerals - Geosciences LibreTexts
网页2022年8月28日 · Mineralogists have described more than 100 sulfate minerals. They fall into two main groups: those that contain water (hydrous sulfates) and those that do not (anhydrous sulfates). Gypsum (CaSO 4 •2H 2 O) is the only common hydrous sulfate.

网页2024年8月25日 · Members of the barite group constitute the most important and common anhydrous sulfates. They have orthorhombic symmetry with large divalent cations bonded to the sulfate ion. In barite (BaSO 4), each barium ion is surrounded by 12 closest oxygen ions belonging to seven distinct SO 4 groups.

网页2019年6月13日 · Sulfate minerals are delicate and occur near the Earth's surface in sedimentary rocks such as limestone, gypsum rock, and rock salt. Sulfates tend to live near oxygen and water. There is a whole community of bacteria that make their living by reducing sulfate to sulfide where oxygen is absent.

Sulfate minerals - SpringerLink
网页Sulfate minerals are characterized by the essential presence of oxidized sulfur, in the form of SO 2− 4 ions. Within the sulfate molecule, four oxygen atoms are covalently bonded to sulfur in a tetrahedral arrangement, to form a discrete anionic species.
