Sulfates are widely used industrially. Major compounds include:

* [[Gypsum]], the natural mineral form of hydrated [[calcium sulfate]], is used to produce [[plaster]]. About 100 million tonnes per year are used by the construction industry.
* [[Copper sulfate]], a common [[algaecide]], the more stable form ([[Copper(II) sulfate|{{chem2|CuSO4}}]]) is used for galvanic cells as electrolyte
* [[Iron(II) sulfate]], a common form of iron in mineral supplements for humans, animals, and soil for plants
* [[Magnesium sulfate]] (commonly known as [[Epsom salts]]), used in therapeutic baths
* [[Lead(II) sulfate]], produced on both plates during the discharge of a [[lead–acid battery]]
* [[Sodium laureth sulfate]], or SLES, a common [[detergent]] in shampoo formulations
* [[Polyhalite]], {{chem2|K2Ca2Mg(SO4)4*2H2O}}, used as [[fertiliser]].
